Just checked for updates & SP3 is out. Hope it cures my woes, at least some...
Well, I installed SP3 & all is good, I can work in 2011 again!!
I had a file(s) that would lock up, it was so bad I couldn't use it. It did that whole build list, destroy, build for about 20 min. until I quit.
Opened those files & no problems at all.
So far so good
