#7 Fix JPopupMenu focus bug

[Anonymous]

With JDK 1.4.0 and above displaying a JPopupMenu
causes the popup menu to gain the focus.
See bug 4470468 on the Java Bug Parade.

Here is the suggested work around...

If you don't want the popup to steal focus when it's
shown then insert this
line:

popup.setFocusable(false);
