[jitter] How to close a grabbed file

Hi

I am using jit..qt.grap and jit.qt.movie after one another. 
I record a camera stream, whereafter I manipulate this with a qt.movie editor.

First time I record everything works just fine, however the second time when I overwrite my sample file the file seems to remain open and then I cannot open it using qt.movie. What message should I use to the grab to close the file? I've tried close, stop and clear.

Included is a simplified patch.
