Hi,
Didn’t see this one.
I use two monitors. I click the “Lock Cursor to Window” option under Interface -> Mouse (to keep my mouse from jumping to my second monitor), but every time I re-log the game my mouse cursor will still jump to my second monitor. When I go back into the options, the setting is still checked so I have to un-check and re-check to get it to work again. Once I do that, it works fine until I log out and back in (as in a total logout- not just swapping toons).
More of a nag than anything game-breaking, but there it is.
