Mouse cursor stays on screen

[Urkle]

Ahh.. was going to ask you if this was a steam or non-steam version.. Though thus far I haven't run into issues with the overlay in steam.

Actually you can download the demo version of amnesia and try it, and that would test the "out of steam" scenario so you could definitively know if it's a steam issue.

You can also right click (ctrl-click) on amnesia in your steam library and choose properties and then uncheck "Enable Steam Community In-Game" (which should disable the overlay) and see if the problem persists.
