Displaying a single bug in Bug Tracker is incredibly slow, maybe 30
seconds before the page finally comes up.
Filtering on the Bug Tracker is largely unusable - the filtering seems
to be doing the job, but the page gives you basically no idea
whatsoever just what it is you've filtered to.
Formatting of Bug Tracker submissions is hosed, it pops up some weird
in-line HTML editor that looks like Microsoft Word, with NO OPTION to
switch to the standard OpenACS submission types. AFAICT it is
impossible to post HTML to Bug Tracker.
