I am using a Windows 10, 64-bit computer. Recently I was playing StoneShard and walked away for a few moments. My screen saver came on. When I got back to the game the screen had shrunk to about a quarter size, was locked in the middle of my screen, but, here is the real issue, the mouse was locked into the smaller screen but was still pointing as though it were full screen (only to the far left). What this meant was that I couldn't use the mouse to select any of my inventory items or target any enemies because the mouse would only point to the left quarter of the screen. Moving and using special abilities was possible because there are keyboard shortcuts for those, but I could not attack, and this got me killed.

Has anybody else experienced this recently?
