Keyboard shortcuts CTRL^Z and CTRL^Y for undo and redo respectively, not working. But, the Undo and Redo toolbar options working fine.
I've noticed this as well. After assigning these in the keymaps options pane and hitting OK they work again for a time but quickly stop working again. I can swap profiles, hit OK, then swap back and hit OK and they work again for a while as well. I originally imported Netbeans 5.5 settings and finally gave up and started from scratch with new settings. Same result.

As a further note: Removing the undo keybinding from org-netbeans-modules-editor-settings-CustomKeybindings.xml does not alleviate the problem.
