Mac OS X Moving Client Between Desktops

I pressed Mission Control (F3 Key) to display all windows, and dragged the LoL Client from 'Desktop 2' to 'Desktop 1'. The screen kept jumping back to 'Desktop 2' even though nothing was there - it would do it every few seconds. I tried using Mission Control to drag the client back to 'Desktop 2' but then the client shot down to the bottom right of the screen and disappeared. Anything I tried to bring it to the foreground only showed it for a brief instance before it shot back down and out of site. I had to quit the client. It seems like even though the client window looked like it moved between 'desktops', the pointer remained attached to 'Desktop 2', and every time the app was scheduled for a refresh it would shoot back to where the pointer thought the client was. Big bug but easy to fix for your OS X developers.
