Win 11 problems

WIN 11 Migration Problems:

New Win 11 computer, HP desktop with Intel 6core chipset. I downloaded the current LBB version from the website. I "run as administrator" and the program editor starts. I load an existing, .bas file that was fully operational under Win 10:

1. The LBB program loads but none of the color attributes appear.

2. The font is very tiny and the Options>Font selection says 9 pt and that's the only choice.

3. The program compiles, but very very slowly.

4. The program runs extremely slowly ... under Win 10, it would run to completion in about 10 mins [involves multiple searches of a very large file]. Under Win 11 on new computer, it ran more than 24 hours and did not finish.

The migration to Win 11 has not been smooth [thank you Microsoft!!] but I've figured out most of the problems. This one has me baffled.

New Win 11 computer

So two changes: Windows 11 and a new computer. I wouldn't necessarily blame Windows 11 for things that may be a function of the new computer.

I am running Windows 11 on this laptop and both LB Booster and BBC BASIC for Windows run perfectly well, indeed exactly the same as they did previously in Windows 10. Under the hood, Windows hasn't changed much since NT 4.0!

2. The font is very tiny and the Options>Font selection says 9 pt and that's the only choice.

What 'High DPI' compatibility settings are you using?

1. The LBB program loads but none of the color attributes appear.

Here's proof that the color attributes work in Windows 11:

Just done some checks following Guest's comments.

1. Scaling doesn't seem to make any difference to performance.

2. BBC for Windows: IDE opens quickly. File loads quickly. Type run and it takes about a minute for the program to run.

3. LBB: IDE very slow to open. File loads quickly. Type run and a window flashes open and closes in less than a second. It then takes about a minute for the program to run.

4. I agree with Guest that colour attributes work.

I would add that when I first installed LBB on my new computer, it worked perfectly, as did BBC BASIC for Windows. I installed various programs afterwards, but I couldn't say exactly when LBB stopped working properly.

I am on Win11, fully up to date. Downloaded LBB, IDE opened immediately, my supertextbox demo opened and ran instantly, less than a second to fire up. I also ran my scrabble anagram search program that works on a big dictionary and it fired up and ran instantly, it completed twice as fast as Liberty.

I run Defender, Windows native virus checker.

I use Eset. I have tried it with Defender, but it doesn't seem to make any difference. My computer was a birthday present in August and I've not plucked up courage yet to take the back off and replace the ssd with a cloned version. When I do that I can do a reset and try again. From memory it seemed to work OK before doing some Windows updates, but I've not used LBB much since I installed it.

Going online and asking the question, we are not alone where app performance has worsened following Windows 11 updates (including the August 2025 update, which is probably about the time I noticed). I have a 32gb machine and 1 Tb ssd, so I wouldn't expect space problems.

I have today swapped the 1TB ssd for a cloned 2 TB ssd. I will clone another 1TB ssd and then completely reinstall Windows 11 and start from scratch to see what happens.

OK, thanks for the comments. I'm sure this is NOT an LBB problem, every speed bump I've encountered in this Win 10 --> Win 11 on the new computer has turned out to be something in Windows 11. One way or another, I'll figure it out eventually. I did manage to get the color attributes and the auto indent working ... sadly, it happened when I was screwing around with something else and I don't know what caused it.

I would make the point that, although I am having problems with the speed of loading and compiling with LBB, LBB once loaded and compiled works exactly as it should. You just have to wait a long time to get the compiled program

4. The program runs extremely slowly

Personally, I'd concentrate on this because it's probably the most important, yet easiest to diagnose, problem. Execution speed of a program which doesn't interact with the OS at all (i.e. uses no input-output or other OS resources) should not be affected by the version of Windows - it's purely a function of the CPU and its clock speed.

So write a program of that kind, for example a simple FOR...NEXT loop with nothing in the loop that will attempt to access the OS, and time how long it takes to run on a 'working' system compared with the 'non-working' system. Assuming it runs much more slowly on the new PC, use Task Manager to find out how much CPU time it is using - it ought to use 100% of one core (so on a four core CPU a total of 25%).

If it is using the expected amount of CPU time, but is nevertheless still running slowly, use a tool like CPU-Z to monitor the CPU's clock speed. Something I've noticed is that, on laptops specifically, the OS will sometimes switch a process to a low-power (and therefore low clock speed) state when it shouldn't. I've changed my settings to run in high-performance mode all the time.

If it isn't using the expected amount of CPU time, it's likely that the OS has suspended the program for some reason, perhaps pending an online virus-check or something of the kind. See if there's any evidence of what that might be, for example what processes are actively running in Task Manager; do they include a security suite?

It's important to keep a clear head and not to be bamboozled by multiple problems seemingly happening at the same time. They may not be a result of Windows 11, indeed they may not have a common cause at all.

This is a long shot, but can you check which release of Windows 11 you have. I am seeing a few reports online of 'strange' effects, including code running slowly, after the update to 24H2. For example this of System Very Slow After Installing Win11 24H2.

It would be interesting, to say the least, if you are not running 24H2 but the other people experiencing LBB running slowly are! I would then have to concede that it is indeed plausible that something having changed in Windows is responsible.

I know, for example, that the implementation of Critical Sections has changed in 24H2, and I think LBB (or BB4W) does use these. Unfortunately, if this were to turn out to be the cause, it's entirely possible that I couldn't fix it, after all this time.
