If (or should I say WHEN) PPro crashes I find I have to open the task manager and end ProHeadless before I can shut off the computer. There is also a file "capture font" that is lurking in the background that needs to be ended to close down.
I have been getting this 100% of the time when I try to encode a specific H.264 video. It fails everytime I leave it on overnight. At least 10 times in a row now. AME prompts me on startup for an "update with this version of PP" in the help menu, but there is no update to select.
