That's why I put the "answer" command as the first line of the closeStack
hander - to see if the handler was being called or not. But it's not. Except
sometimes. And the sometimes seems to have something to do with the state of
the video grabber window.

Are there any extra commands that can tell us whether the video grabber
window is even present or not?

Also, what is that first (and undocumented) parameter to
revInitializeVideoGrabber, as in the video stack example:

revInitializeVideoGrabber the short name of this stack,"qt",iRect

for? The docs only show 2 parameters.

I think both these issues are connected somehow because I don't have similar
problems when closing other stack windows.
