If you hit Stop before closing it, it *should* work.
I was having problems thinking of the best way to close it.

Currently when you hit stop, it sends a # packet which gets intercepted and runs gst.CloseMainWindow(), but it doesnt seem to work every time. gst.Close() doesnt seem to close it at all, might have to Process.Start("kill " + gst.Id).

Dont know how "proper" it is to do that, though.
Also, a problem with smartcam, it doesnt seem to work on some flash based sites that use the webcam; eg; tinychat.com, it shows smartcam as disconnected or something, if you choose it anyway flash crashes.

But yeah, other than that its worked in everything else.
