Well I finally upgraded my FMPA 14 to the latest update 14.0.2 over the weekend. While the problem with script lines moving around appears to have been fixed, I am still getting the actual scripts themselves (in the left panel) jumping around. I even had a couple scripts completely disappear on me yesterday (the search function could not even find them). I closed the application and reopened it and the scripts were back, but had been moved to the end of the list.
I am using FMPA 14.0.2 64 bit, on Windows 8.1, Lenovo laptop with Microsoft 4000 mouse.
Please fix this!!! It is extremely frustating.
