I have been trying to troubleshoot the source of some duplicating tooltip information I have been getting, to no avail. It seems to only happen with MobInfo's Tooltip and Fizzwidget's FOM. I also have Mendeleev, BOC and ProfessionsBook inserting info with no issues.
I use CowTip for my base tooltip if that helps at all.
If anyone else has had this problem and been able to solve it, I'd be much oblidged.
