(Everything else I mentioned earlier seems fixed - thanks!)
I attempted to add a default query, and I got:
insert into queries values (4, : parse error near '' at line
1 at globals.pl line
Please send mail to this site's webmaster for help.
(The query I was setting as the default was just
'Red Hat Linux' and 'Raw Hide'; no categories/status/etc.)
This was fixed in the last furry of code updates/fixes/etc.
