Screen Saver killing my application

Hi,

I have a standard EXE that calls another ActiveX.EXE. Recently I noticed that when my screen saver kicks in, and I shake the mouse to get rid of the screen saver, my application that was running is killed. Anyone ant clues where to start looking?

regards,
Darrell

Sorry, I should also have said that I'm developing under NT4, using VB6, and the screen savers are the standard NT ones.

regards again.
