Hello..some of my kinmates are having problems turning their toons and warsteeds using their mouse. They end up using A and D to turn. I have always used my mouse to turn my character. I can turn on a dime and find that invaluable in mounted combat. I watch my kinnies try to turn their warsteeds using their mouse and just the head moves. It looks like they are TRYING to move but can't. Today, I logged into one of their accounts from my computer and had no problems at all. So pretty sure it is a mouse setting that needs to be changed at their end. Problem is.........which one? Any suggestions?

Thanks in advance!
