I'm running FrameMaker v126.96.36.1991 and whenever I try and create a pdf file it gets hung up. I end up having to kill the application through task manager and try again but nothing seems to get me through my issue. I have limited access to my laptop and being able to change system settings. This is a new version for me but not new to this laptop. The laptop is new and came with this version of FrameMaker. That's probably not relevant but I thought I would share.
In my experience, unless Windows tells you that Fm has crashed...it hasn't.
Of course, that doesn't mean you have the time or patience necessary to let it finish the processing. I've had numerous jobs complete after 6 or more hours of processing. Worse, I've had the process complete, but then had Fm locked for an hour or more after the processing is finished, and I've accessed the resulting PDF.
