Take a saved query and choose to load it rather than run it. The saved query
does not include the form=advanced option, so it loads it in the simple form
which cannot display most queries that anyone would bother saving.
Red Hat's current Bugzilla version is 2.18. I am moving all older open bugs to
this version. Any bugs against the older versions will need to be verified that
they are still bugs. This will help me also to sort them better.
if the format= is left off the default is the advanced page so this should no
longer be a problem.
