Well, the 1.5.0.2 update runs fine for me. It does, however, break my ability to use Flash, or to reinstall flash, althought this may be an issue with macromedias site and not PFF. (says server not found.)
I use flash alot. My school uses it ALOT for instructional materials. (Flash papers).
And our school online learning center has flash elements that i can no longer use, not to mention Student Services.
I tried a fresh PFF installfrom sourceforge, did NOT install my extensions, in case one of them was the culprit, and updated to 1.5.0.2. Again, it broke. I luckily had a fresh backup. ( Monday night is my backup night, PHEW!!!).
