I personally have no idea but I remembered a section about this in one of the stickies so I thought I'd just copy&paste it in case it might help.

""Secondly, it might be an idea to add a bit in the keyclone setup section about "run aways" i.e. if people add
wasd (or whatever they use for movement) to their no?pass list pressing a modifier key (shift/ctrl/alt), then a
movement key, then releasing the modifier key before the movement key can cause your followers to get that
movement key"stuck" down, making them run in that direction till the key is pressed again on each char. So i
would say to add the following to the no?pass list aswell."
left/right alt+w/a/s/d
left/right ctrl+w/a/s/d
left/right shift+w/a/s/d"
