Here you go.  I believe the problem stems from the program running in
a separate thread.  When the mouse cursor crosses the separator in the
table header, the cursor will change to a left/right arrow while it's
in the separator.  When it does this (while it's in WAIT_CURSOR mode),
is what I believe is the problem.  Once the cursor changes in the
separator, it's forever stuck in WAIT_CURSOR mode after that.  Can you
verify this before I submit it as a bug?

Thanks,

Dennis
