I had to wipe my computer and start over on August 27. On August 29 I installed FS and my camera movements would not work properly.(I use Ctrl Alt to move my camera not the built in thing) I then uninstalled and tried it on V2 same issue. I am not sure if this is a computer thing or a SL thing. I do not have any other issues with my mouse on anything else I do on my computer, just sl. When I hold down Ctl +Alt+Left mouse to pivot around my selected object the camera will start to spin really fast out of control and I end by looking up at object. (it will only pivot counter clockwise) It will not let me pivot up or down with the mouse. Also When I click on my target then let go of the buttons the mouse will jump to the left of my target. (same spot every time, like its has its own screen center point) When I first loaded up FS I set all my movement settings to normal. When that didn't work I defaulted everything and still no change. I then uninstalled FS and reinstalled V2. Kept all the settings at default and Still no change. I am running Vista, Mouse is a Logitech mx518. I have gone into the mouse settings and I do not see any option to calibrate the mouse itself to see if it maybe is off center or something. I have also tried different screen resolutions to see if by any chance that might have something to do with it. I know this is a v2 help, but I figured since I am having the exact same problem for all the viewers someone could help me. I am just not sure if it is a problem with my computer, but if anyone can give me a suggestion or help I would be appreciate it.
