I opened tabs for AddOns, email, Search and so on, but they refused to close until I Disabled this addon.
This review is for a previous version of the add-on (3.1).TB60 support has been submitted awaiting review. Let me know if you have any further troubles. Hopefully this fixes your issues. Thanks for your patience.
