When coding in the editor and swapping current window with ALT+TAB and returning to the NB window the mouse pointer
stops in the File menu item of the main Netbeans toolbar. Seems like Netbeans thinks ALT key was hitted.
User expects pointer on the editor at the position where him left before.
Long reported and known JDK/Swing bug, see duplicate 73960.
