As the topic. It happens only intermittently, though when it happens, it usually does so many times in a row. I have windows 2000. I'm using a theme of my own, though its very rudimentary so it is possibly an error on my part. I have the latest stable indiestep (ILS-2003-02-09). Its loading shortcut2.dll, popup2.dll, systray2.dll, grdTransparent.dll, sysvwm.dll, desktop2.dll and taskbar3.dll. It also has died when I'm clicking on the vwm. theres nothing complex in any of the rc files. could anyone help me figure out how to locate whats causing this?

Litestep: Exception in main thread message loop; hWnd = 0xB090E; message = 0x23E1, classname = TApplication

- do you load modules threaded ?
- do you have a zero width or height module ?

I'm sorry, what do you mean load them threaded? And I don't have a zero width or height module.

No I've not been, I tried it threaded just now, and none of the controls responded. The shortcut didn't refresh, and the vwm, and taskbar just sat there and did nothing.

0x23E1 is LM_LSSELECT, which *should* cause no harm... but apparently it does. The only modules that seem to use it are desktop2 and taskbar(3).dll. Try replacing one of them temporarily and see if it helps.

ah, you're right. It was taskbar3.dll. I found a newer build of it that fixed the problem. thanks! its nice and stable now, though slow sometimes refreshing the desktop.
