I set up a couple of scripts to drive the SNAP port of the AZ-GTi in order to fire a DSLR using the CCD Simulator: A "SNAP ON" script is called on Pre-Capture and a "SNAP OFF" script on Post-Capture. It works perfectly when exposing a sequence.

However, only the Pre-Capture script is called when doing a preview exposure. The same happens when framing (looping). Likewise, the Post-Capture script is not called when an exposure is aborted (either during a sequence or when aborting a preview or framing sequence).

Right now, I have to call the "SNAP OFF" script manually from a terminal window whenever any of the above happens (pressing the "stop" button would be so much easier :).

Is there a reason for this behavior? Is there a simple way to modify that?
