Help! Play avi files with mciSendCommand but screen become black after 5 hrs

[sabrinatunha]

Hi,

I have a multi-thread application in which I use mciSendCommand to play avi files when the application is in idle. It works perfectly in winxp, but when running in windows 2000, after 5 hrs, the screen becomes black but the voice still played correctly. The memory seems growing a little bit and application still alive. If I try to focus on other application and come back to this application, it can play normally once but will be black again.

Is there anyone can help me to solve this problem?

Thanks!

Sabrina
