SWTOR Keyboard movement keys

Not sure if this is out there asked already. I have seen some older (a few years) topics on it but thought I'd ask again. During gameplay my movement keys A,S,D and W just seem to randomly lock up. The game itself doesn't seem frozen because other things are still happening. Combat continues, interactions....etc. I tried turning vsync on as I saw in older post but didn't seem to help. Any assistance is greatly appreciated.
