Sleep() is redundant.

Very much too restrictive. Use QS_ALLINPUT instead.

Again, too restrictive.
You say mouse and keyboard are locked, that would
be because you are only looking at paint messages.
Use general message pump.
while ( PeekMessage( &msg, 0, 0,0, PM_REMOVE ) )
{
TranslateMessage(&msg);
DispatchMessage(&msg);
};
