I'm using Build 2143 on Win 7 x64 and when trying to Undo Ctrl+x and Redo Ctrl+y nothing happens, but if I copy the key bindings in to Key Bindings - User they will work.
Wow still no reply after this length of time
Just tried with the latest build and it's still the same.
What exactly is the problem? When you cut something you can't undo it?
