Windows 10 FMP17 (updated to 22.214.171.1240 - no difference). What I've noticed is that FMP17 will load after a fresh computer start (or reboot). Then when I close the application (either by script step or clicking the X), and nothing is left on the screen or on the Taskbar. I notice that it is still running in the Task Manager. As long as that "ghost" task is there, FMP17 will not start again. If I end the task, it will start. So there is a work-around, but it is a pain. Funny thing is that occasionally quitting FMP doesn't leave a "ghost" in the Task Manager.
