I picked up the Steam version of [Serious Sam's Bogus Detour] the other day, but I'm unable to use the game so far, as the mouse buttons drag the cursor immediately to the top left of the screen whenever they're clicked.
I made a post to the Steam discussion page stating the issue, to which a dev responded he/she thinks the mouse is being detected as a joystick.
I've made a few attempts to google such things, but the few discussions going on about vaguely similar topics (of which there don't seem to be many), frankly, are going over my head. So I've not managed to find a simple and definite solution I can grasp and implement.
Has anyone had a similar issue or knows a way I can figure this out and track the issue through to the point of fixing it, because I'm kind of limited in what I can do?
