Description David Pickens 2005-04-20 13:59:57 EDT

I started getting this in 3.1M6 when I attempt to edit some Java source files.
Its happened more than once. Though I have been using 3.1M6 since it was
released, this is the first time I have encountered the problem. The work-around
is to do a "Close all" first.
