Pariksheet,

Thanks for the reply.  A few days past, I was able to
to find a work-around.  I would have followed up my own
post but as there were no replies in a week, I assumed
(incorrectly) that the thread was dead.

Succinctly, the problem has nothing to do with ImageJ.
I was seeing it only with ImageJ because that is the
only way I normally come to have more than 7 windows
open at once.

It is a Gnome bug.  When one uses a vertical panel,
the bug is triggered on creation of the 8th window.
I have re-configured my desktop and moved on.

For a detailed explanation see Bug #187540 in Launchpad.

Regards,
Ray
