Interesting that support would ask about an SSD. I never called support, given all of the stories here. The SSD thing was just a theory as I was thinking about the differences between my two computers. If you don't have another machine and want to test out the timing hypothesis, another idea would be to get an external spinning HD, put your TT file on that, and try saving to PDF on that drive. It's not a perfect test, though, since it's possible that TT is using the boot drive for temporary files, but if you don't have access to another PC it may be worth a shot.
