Waiting for a Splash Screen

MFC++ 5.0 Win 95/NT4

Hi;
I use a call to SetTimer to display a splash screen when my app first starts. I want to suspend the program until the splash screen is deleted. I can not find a Pause function. A while() loop that waits for the dialog to disappear hogs the processor. This should be simple.

Thanks

void Sleep ( DWORD dwMilliseconds )
