Works, but touchy. Mouse needs to be close to, but not at-the-edge-of the game window to scroll.
Would be nice to have an adjustable sensitivity.

It works, but if there was a button to Activate/Deactivate this so I could play normally, then activate when I want my mouse to leave the screen and reactivate when I return, that would be great. In the meantime I find it unusable because the edge line is too fine. Are there any adjustments or an option panel for this? .. I cannot see anything for it. This is such a great idea!!

Work's well
