Description ecastro 2009-05-04 10:38:28 UTC 
Build: NetBeans IDE 6.7 Beta (Build 200904242137)
VM: Java HotSpot(TM) Client VM, 11.0-b16, Java(TM) SE Runtime Environment, 1.6.0_11-b03
OS: Windows XP, 5.1, x86

User Comments:
ecastro: I was pressing CTRL+ALT+H to get the Find Usage shortcut.
However, I have a strange keyboard layout (designed with MS Keyboard Layout Creator) in which CTRL+ALT+H produce '?' (left arrow).
I guess that it is the source of the bug as it does not reproduce when using a standard keyboard.

It is a known bug of incorrect resolving of TreePathHandle/ElemenHandle. Most likely a race condition.
