I so feel your pain. It is so hard to record gameplay of rooms and such when the character is sprinting and stumbling over when toggling walk.... That said, there is a setting you can change in game to enable a press to walk, or toggle to walk, HOWEVER I will note that the toggle switches back off as soon as you stop walking. which is annoying as all hell. So what I do now is I have my walk animation set to a keypress instead of toggle, and I set it to my Mouse button 4, so, granted I have to hold it down to keep walking, but it at least works for now as I can stop and then start walking again as long as I'm still holding the keypress. I wish they would make the "toggle" an acutal toggle that is perminant. Toggle perminant walk on, and even if you stop walking when you start again your still toggled on, until ya hit the toggle again to turn it off... That is how it needs to be.
