When pressing space bar to bring up the hand tool to move around in the puppet pane it the proceeds to play the timeline after releasing where you want to be looking at on the puppet. Sometimes this results in this error for me.
Adobe.FaceTracker.js:1320 :illegal access
The error does not cause a crash, just pops up and I have to click okay.
Hi Dale... The issue of playback starting when you try to do a spacebar-pan in the Puppet panel has been fixed in the upcoming Preview 2.
I haven't been able to reproduce the "illegal access" error, though. Do you recall if this appeared after you stopped panning or stopped playback, or while panning/playback was occurring?
