We're still waiting for the IT guy to come and install it. I hate when an update requires admin rights
A couple of other trick I have found is if you select other object (while still highlighted) then select the one you want to edit. Then you can deselect everything. Sometimes that works. A few times zooming out and back in will work.
This is one of two major problems we where having. We also couldn't print from model space to our 1050c.
