Mouse Problems - Deadzone

[RYSLYK]

Drivers up to date and an extremely stable PC.

When I play Krater, within 4-5 minutes it seems the game gives me a 'dead zone' in the bottom left portion of my screen. This area becomes completely un-right-clickable, making moving a PITA when you want to move a character there. A restart of Krater fixes the issue, but it comes back again very quickly. I'm suspecting a menu overlay bug. Fun game, I'm enjoying it. Apart from this annoying issue. Curious if anyone else has this issue.

Running 1280x720 in windowed mode. (id like to go Fullscreen but 1 Fullscreen option disables my second monitor from displaying or the other Fullscreen option moves the game to the secondary monitor and off my main. Sigh.)

Are you by any chance running Bing desktop or a similar thing ? it will force itself to the top layer of the desktop when playing in windowed mode creating the problem you describe.
If you have, the solution is simply to turn it off when playing Krater and krater should then work without issue.
Another thing you can try is to set aspect ratio to Auto in the settings for the game (if they aren't already)
