As the title says, I have a bug that seems to have come up with the camera strafing on one of my games - depending on which way the camera is facing, I can scroll with (both mouse and keyboard) either down and right or up and left, but not all four directions at the same time. Every saved game in that group seems to be affected, even one I saved yesterday...Others from previous games seem to work fine though. Mouse and all my keyboard functions seem to be working perfectly fine outside the game.
Every so often it will let me scroll a tiny bit in one of the non-working directions if I try several times, or let me (for example) scroll left a bit and then scroll right till it gets back to the starting point and seems to hit an invisible wall.
Already tried deleting the uimapping file as suggested for another scrolling bug fix, but that had no apparent effect. Ditto for restarting the game multiple times and rebooting my system.
Running Windows XP Pro, latest version of Sins. Thanks in advance for any help.
EDIT: Also tried uninstalling the game completely, then reinstalling and copying the saves back over, but that didn't fix it either.
