Has anyone else had and solved this problem?
you missed a big jump in 3D window functionality with the 9>10 release. you're now in at the deep end with 11!
there are several ways of opening the 3D window now - check out all the different commands, assign the one you use the most (typically 'Show Selection/Marquee in 3D') to your old 3D window shortcut keys and you will be away.
having jumped from 9 to 11, you may find it worth re-reading a lot of the manual before crying foul!
