OK.. I just ran into the same problem.. it was after I went to a heavy laden JAVA site.. after that I closed netscape with the mouse and it was still in the background, I had to resort to a "kill -9 <pid>" to kill it. It doesn't happen that often.. only when the system has been loaded close to the maximum for a while.
