I always experience these things whenever I'm playing:
Randomly or on load screen it shuts quits the application and gives me a error warning...
When I'm running around or typing in prices in WW when I go to chat or pm someone it puts in all of the numbers or letters that I put in WW etc...(This is weird.)
Sometimes when I click on the Nav Bar or power tray they randomly pop up in a different place on the screen and I have to move them back.
Any of you Mac users have any of these problems?
EDIT:
I also have incredibly terrible lag in SuperGroup bases and so I reload the graphics and it still it terrible even if I turn down the graphics.
