Thank you so much for your help.
Once you wrote it down, it was obvious really: I did the ctrl/alt/delt command, shut down the offending prog, then went and deleted it, which it was now able to do, seeing as Windows wasn't using it anymore! All problems are gone- no more hanging when opening & closing files, no more hanging upon shut down. Brilliant!
It's always good to have someone being sensible when you are all in a tizzy, so thanx for being there!
Big smoochies!
