Same thing happens to me on a daily basis, multiple times a day. Seems to happen a lot when I jump into battle with my JK. After the leap I just keep going. It's pretty annoying. To correct, I always have to tap the button assigned to the direction that my character is running a few times to make him stop. First time it happened I had logged in in a cave on Taris to try out my new MMO mouse with fresh keybinds. A random group walked up and asked if I would like to join them so I accepted. In the first battle, I ended up running backwards and couldn't stop (I was jumping and pushing forward furiously but to no avail), and ended up backing myself into a pit of green toxic sludge and dying. I was really embarrassed. I remember the people in the group finished off the mob, then all turned their avatars and walked toward the pit as if they were trying to understand why I decided mid battle to backward suicide into the sludge. I sheepishly explained that my new mouse keybinds went nuts and told them to move on without me. Since then, I've been able to correct the issue faster, but its still something I would like to see fixed.
