By any chance, are you using Firefox as your browser? For some months it's been giving me fits which I think are related to Flash.

Yes, that's been my experience as well. In fact it's trying to take my machine over right now and I'm sure if I checked I'd find both apps using several times the memory they should for the 2 measly tabs I have open, neither of which should be taxing anything. Often after I terminate them and re-start, they behave, but that's a step I shouldn't have to take. I've tried Chrome and don't care for it...am open to suggestions.
But I am also sick and tired of Flash wanting to d/l a new version of itself every time I boot up...anything that has to update that often -- that isn't an antivirus, anti-malware, etc -- has to be seriously messed up. Hence my glee that RR is going to stop using it!
