Form foreground freezing up...

I've got a program that is heavily processor intensive when it's being run. At seemingly random intervals, the program's foreground locks up and doesn't refresh until it has completed its processes. The lockup doesn't occur every time the program is run, though rest assured it will occur if the program is run long enough (usually about 45 secs). In addition, it always happens if I switch to a different application, whether I switch back or not. I assume it's a problem with Windows, but I haven't been able to find a workaround. Neither Refresh nor sleep statements make any difference.

I assume that it's a problem others have encountered. Anybody know a solution or workaround? Or even a cause?

I'm running Windows XP.

Thanks.

You may try Dispose more often. The GC is hanging your machine.

Hi,

Aren't you using worker threads for executing the long-running methods?

Hi,

Check your app's memory usage in Task Manager - is it consuming an unusual
(and growing) amount of memory?

Most of my ideas seem usless or stupid, but I think expressing them here doesn't harm much. This is an idea for Py 3.0, because it's not backward compatible. Dicts and sets require immutable keys, like tuples or frozensets, but to me they look like a duplication. So the idea is to remove tuples and frozensets (and replace the few other uses of tuples with lists, like the % interpolation), and to add a freeze operation, to freeze lists,...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
