This tiny addon will stop you from crashing due to the cogwheel bug which commonly occurs when mousing over things like mage tables, soulwells, feasts, and the Headless Horseman's pumpkin.
All this addon does is stop one-line tooltips from appearing, so most useful tooltips will be intact.
If you still get related crashes then please submit a ticket stating what you were mousing over at the time of the crash.
Fixed TOC file, stupid mistake by myself.
Now only affects tooltips in instances, as it was also stifling character sheet tooltips.
