Mine looks exactly like your image (same checked boxes). As a matter of fact, when I go to that particular tab (pointer options), the little bar for pointer speed moves to the right on its own. If I go to the second tab, pointers, it goes to the last option in "schemes".
I deleted all my browsers in case something was causing a conflict. I've tried three different mice so my guess it's not a mouse issue. Major problem seems that it sends browser windows to the right (when possible), documents to bottom of page and drop down menus to last option. If I try to move the browser window back to center or left, it tries to force it back to right. If I try to select an option that's not the last one in a drop down menu, it's impossible.
I've asked a few IT people I know and everyone is stumped. An IT guy from a school district did tell me that he's seen this problem with Windows 7 and hasn't figured out a fix. Only thing he knows is that it's random (hasn't seen a pattern why it happens).
From my searching in Google, I have yet to find a fix solution that I haven't tried.
Thanks again
