Crash related to Energy Saving Options

Alright, I have an app... A plain old window, created with my wrapped WindowClass.

It runs just fine, no problems ever...

Well, I opened it up and left it open, went and did some stuff, came back to the comp..my moniter had turned off due to the energy saving options I have it to turn off in 10 minutes. So I moved the mouse to restore the screen to see that my app had an error. The rest of windows didnt' redraw from this error, so I had to restart.

To proove it was the energy saver turning off the moniter to cause the error. I set it to 1 minutes, opened my app...as soon as it turned off, I moved the mouse to restore the moniter and the error was there.


This is a plain window with a few subclassed controls.

The only GUI I use would be Begin/EndPaint on WM_PAINT for the window.

Is there a msg I need to handle in WNDPROC to deal with MoniterSuspension??

No, there isn't. There's one you CAN deal with, but none you MUST. (Just think of all the apps that would crash because programmers neglected it.)

Very weird... is there any chance there is a message you accidently handle that you shouldn't?

Start the app in debug mode and let it run until the screen turns off, perhaps the debugger catches something.

It seems this is one of those "creeper bugs".

Only now and then does it occur, and ironically I am now having a problem creating this crash. After a few restarts due to the problem, is sorta disappeared....

All I ever have open is WindowExlorer, Msn, VC6, Mozilla, Winamp.
So maybe one of those created a conflict.

Multi-threaded app? It could be some sort of concurrency bug.
