[BUG] MAC In game movement

This recently started to happen when I upgraded my Macbook Pro's Software to OS X Mavericks; once I log into a game my viewing square will not move and I have to double left click for anything to happen.

I can my my character within my viewing area but when i want to move past my viewing space it just simply won't go. This has happened in the past but I would just reconnect to the game and the problem would go away. However now even after I reconnect the problem is still happening.
