Ok, I was just grasping for straws and trying to find the magic bullet that
would allow Eclipse to know that the file was modified and have the
underlying system release the file handle.

Correct, there's no exceptions happening.  All that handleException() does
is show an error popup with the message from the thrown exception.

Unfortunately, I can't run in the workbench debugger.  When I start a
run-time workbench,  the only projects available to me are "Simple", no
"Java", and even so, I cannot create files within a newly created simple
project.  It's strange because my eclipse install on my home machine allows
me to debug plugins and create Java projects for testing in the run-time
workbench.  They are both ver. 2.1.  If you know a way to fix my run-time
workbench please advise...

So when I work on this plugin on my work machine I am reduced to "printf
style debugging" via MessageDialog.showInformation().  :(

Here's what shows up in my .log though:

!ENTRY org.eclipse.jdt.ui 4 0 Apr 17, 2003 09:15:09.655
!MESSAGE See details
!SUBENTRY 1 org.eclipse.core.resources 4 273 Apr 17, 2003 09:15:09.655

Unfortunately the formatter utility is third-party and I don't have access
to the source.
Again, thanks for the help.
