Flash is bastard child even on Windows computers.
I have a Win7 desktop that is my mainstay, and Flash crashes almost every time that I try to view something with it.
I have chosen to use a very old copy of Chrome browser on my Win7 desktop which has its' own internal Flash viewer. I refuse to update the damn thing because at least it works.... I subscribe to a newspaper that runs in flash only up until 2 months ago, when they finally, thank gawd, switched over to PDF downloads being available.
