I had an issue with the controls a few minutes earlier, which is probably the first time I've had problems with controls in many years. Granted my controls did not die, I was simply locked into walking forward (forward being wherever the camera was pointing.) My keyboard controls still functioned normally beyond that (which was strange because autorun/autowalk did nothing, my inputs took priority, and I have nothing else plugged in atm.)
Going into the options and turning the keyboard controls On>Off>On fixed it.
I started using the widescreen client today so, take from that what you will. I play a billion other games and am somewhat versed in the computa blahblahblah
