I must have woken up stupid last week and am in need of help! My default AB321 and Add-On POSKY B757 2D panels do not appear and I have no idea where to start the troubleshooting. I have tried cycling through the 'A' options and can see the 3D panels and other views, but no 2D panel. Any help / suggestions would be appreciated.P.T. Smith

Check the transparency setting in the Display options, it's probably down to zero.

Ryan,Thak you very much! That was exactly the problem. Now I have to hunt down the guilty one.
