this was a problem for me in DoS1 also. go to turn volume down and char goes into sneak mode. and Yes ive rebound keys and all that. and yes ive played on many pcs. 4 that i can remember.
i thought it would be ironed out by the time DoS2 came. but not for me.
anyone else have this? i was surprised i got no results on searches. could i really be the only one?....

edit;
oh yeah, and "Mute" key pans right.
