It is CGI.pm that is the culprit (when you call $self->query you get a
CGI.pm object back).

You would think so, but CGI.pm has a different idea in this case (that
I have disliked from day 1).  This is called the sticky forms feature
of CGI.pm where the parameters that were submitted in the last request
are automatically set for you when you create your form widgets (which
in itself is not that bad).  The problem is that CGI.pm completely
ignores any new values that you give to the widgets unless you set the
'override' switch.

You are not the first, and I guarantee you will not be the last.  This
issue has caught a lot of people (some, like me, have even been caught
by it multiple times over the years ;-) ).
