Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have found that if I've been editing a file for a while, for some reason
at
some point the rectangle functions stop working.  I can't figure out any
pattern, and I didn't think of generating this bug report at the time.  It's
happened quite a few times since I moved to emacs 21.1 (on NT 4.0).  Has
anyone
else seen any problems with using rectangles?  One typical use I have found
is
for deleting a column of data from a table, but the table isn't really in a
formal table (as defined in tables.el).

I use the rect-mark package from Rick Sladkey, in case that makes any
difference.  I can include my .emacs if needed.
