I am running a Dell M4500. SW2014 just started showing a transparent GUI. I can see all of the menus (file, etc on the top bar), but the actual display area is totally transparent.
I have been running 2014 almost from its inception. Graphics card driver was updated to try to fix the problem. I still have a copy of SW2012 on this computer and it runs fine so.....
Any ideas? Went to Dell's product support site and since I still have a warranty, I was able to do an extensive diagnostic on the video card and everything passed.
