so I have a mouse problem. it feels locked to the x/y axis and small movements don't register, I don't have a joystick in, I have no problems in the other gog games I have.

I got it working once by uninstalling the mouse device then just using the windows hid driver, this worked for one session but after a reboot its back, and no amount of uninstalling or reinstalling the driver works anymore.

I also have removed any Logitech software running this also seems to have no effect.

same problem - MX518 small movement lag

Well, this thread was for a different game, but the last post has some ideas that may help: http://www.gog.com/en/forum/constructor_series/mouse_movement_is_buggy
