The problem is: the view cube doesn't respond and the navigation pane/tool/group doesn't respond either. If i click on any of the tools it doesn't register in the command line.
The view cube stops working after some amount of time (or clicks) regardless of what I've been doing. If I switch to another drawing the view cube works fine there. If I close the (not working) drawing and open again it works fine.
The views under view work.
I guess Autodesk doesn't seem to care to fix this issue. I'm using all the 2013 suites and the viewcube still stops responding as with the other versions.
This is a real pain in the rear.
Lets hope they get it fixed soon.
