What add-ins are loaded?
Problem
You suspect an add-in might be causing problems, but don't know exactly what addins are loaded.
Solution
You can choose Tools, Add-ins to see a list of currently loaded add-ins, but be aware that this list doesn't display all loaded addins.
See What add-ins are loaded? for a VBA macro that'll list all loaded add-ins including COM add-ins.
