NetBeans user has reported the following issue:
This bug occurs with the NetBeans IDE 7.2.1 on MacOS with Java 1.7. To
1) Close NetBeans if open.
2) From the "Displays" MacOS dialog, set the screen resolution to some lower
resolution than the maximum/preferred one.
3) Start NetBeans and maximize its window (green traffic light button on top
left-hand corner of the window).
4) Now set the screen resolution back to its maximum. The NetBeans window
remains the same size, and cannot be made larger (by dragging nor by pressing
the maximize button again). The only workaround I have found is to restart the
jEdit, another Swing app, does not seem to suffer from this problem. I was,
however, able to observe the same behavior in a test Swing app I made, so it's
probably related to a JDK issue.
