Having an issue with the attack - left mouse button. Basically, the left mouse button now zooms the camera in and out like the "F" key should (and does). I've tried a different mouse, I've tried resetting the controls, I've tried uninstalling the game, delete the Steam folder and the FO NV folder in C:Documents and Settings/User/My Games and reinstalling. No change. I checked Fallout 3 and of course the left mouse button works perfectly for attacking. I have a sneaking suspicion that Steam is storing some corrupted .ini information off line and I can't delete it to start from scratch. :brokencomputer: I have tried remapping the attack command to another key and of course it works, but I need it on the left mouse button - its just not handy anywhere else. Any ideas?

On an unrelated side note, I hate Steam. I thought Beth blew it with GFWL on Fallout 3 but its a dream compared to this.
