Do you start game from "Metro" or from classic desktop?
I had some issues with older software (custom one) started from "Metro" start menu on my test station...
I've done both with no problems. Although I need to run it from the desktop because of having 2 monitors and TOR unlike other games does not lock the mouse to the monitor it's on. So I have to use a cursor lock program that made a special start icon for TOR on the desktop. But running from the Metro didn't have a problem outside of the cursor not being locked.
BW, this is the end of 2012. Join us from the 90's when people only had 1 monitor on their computers.
