Return of Reckoning

So i was playing last friday and when i logged my SH i noticed something strange. If i right-clicked on the ground, a green cross would appear and my character would move over there (think Diablo, Baldur's Gate, etc.). I have no idea what causes this (a certain setting, an addon, etc.) but it is really annoying and i would appreciate it if anyone could help me deactivate this feature.

The only thing i changed (before this thing happened) was going from window mode to ful-screen, but i have no idea if this has something to do with the problem.

Have you got 'click to move' checked in general settings?

Click to move. So you can play one handed. Probably aimed at those playing witch elves.

Thanks for the replies.
