Settings page

[Alarion]

Alright, I'm having quite a bizarre issue with the game. I loaded it up, opened the settings page and... couldn't move my mouse out of the "video settings" page. I tried with the keyboard, but it refuses to make any constructive changes - when I went up to "sound settings" it pulled everything to 0, and the same with any other setting I could access. If I try to move the mouse it sort of "snaps back" extremely rapidly to a certain point in the corner of the screen. I'm not sure if it would be different if I actually started the game, but I don't really want to run it with no sound, lowest texture detail and a wonky (1600x900) screen resolution... What could possibly have caused this? Thanks...
