I still don't see that as a bug.
Stop button doesn't stop video - I'd like your definition of a bug - actually that rhetorical
You can if the preview window is not active...
Maybe it's my machine - or maybe no one else uses stop button but you cant
A recording is playing away 'full screen' and i press STOP - Home screen pops up and recording keeps playing in preview window - only way i can stop recording is to press TV - this doesn't happen all the time but at least 50% of the time
like i say maybe it's just my machine that exhibits this peculiar behaviour
