So, I played at lunch time, I play on PS3 & PC W/ Gamepad - I cannot imagine me having not used autorun (I wasn't really thinking about however, so I can't guarantee that I did use autorun)

What exactly is the problem? This thread is filled with "Fix this problem" but doesn't really say what the problem is.

You are running, you want to zoom out the camera
you press L1 and pull back on the right joystick
Your character starts autorunning - is this the problem?
tap L1 and you are no longer auto running. - This is the 'fix'?

I'm trying to think, as occaisionally mine has been buggy and I didn't stop auto running, but that was pre 2.1. I guess I'll find out tonight.
