We are still running SW2011 SP4.0.  A few years ago we got burned pretty badly when we upgraded early.  This year I have been waiting around to upgrade to SW2012.  I noticed that SP2.0 came out the other day.  Now that it has been a few days, I was wondering if the Toolbox problems were fixed and how well SP2.0 is operating for those of you guinea pigs that have already accepted the challenge?  Your responses (good or bad) are appreciated.  Thanks--Tony
