WaitWindowEvent "freeze" my software

I run a windows software that saves picture from my webcam every second.

I don't need to use the software once running, the problem is taht it seems that WaitWindowEvent disable my software a few seconds (3 to 6), and as soon I move the mouse on my software windows it goes back to life (saving a picture each second).

My CPU is not overloaded (2% maximum). XP SP 2. PB v4.00

Any tip ? (without using threads please because I'm a beginner).

Hi,
we need some code to help you

WaitWindowEvent() halts the program until input events happen (thats why moving the mouse over it helps)
Just use the command with a timeout like WaitWindowEvent(200) which makes
the command return after 200 milliseconds even if there were no events.

Thank you very much freak now it works 100% !.
