--- Comment #12 from Josh Jones joshorjeff@gmail.com 2008-10-07 11:52:20 --- Can anyone think of a way to disable the minimap entirely, rather than just hiding it with an addon which doesn't seem to solve the problem. It seems that the bug is directly associated with the minimap. In old WoW releases you could override parts of the Blizzard lua code using a FrameXML folder, but nowadays this seems to just renamed at each run to FrameXML.old and ignored.
Since the patch will probably be released in a week or two, I'm keen to find a way to continue playing without having to shell out early for a new graphics card.. :)
