My direction control sometimes locks up while playing. For example: I'll be fighting and hold fire (Left mouse button) to charge my attack, and while I hold the charge attack my direction of movement (mouse aiming) will be locked! I can still move forward and backward, but I cannot turn side to side to aim my attack.
I use WSAD to move relative to my mouse pointer, I don't use directional movement N S E W. I aim with my mouse and move toward the pointer with W, away from the pointer with S, and straffe left/right with A,D, respectively. Right click is shield.
This happens 3 or 4 times a day. It's very annoying and has gotten me killed or almost killed many times. At first, I thought It was just my mouse, but it does it on all 5 computers I have at home, each has a different type of mouse.
The LOCKED HUD is broken in some areas of the screen. I've marked them on a screenshot: http://img15.hostingpics.net/pics/8623582012052600009.jpg
They introduced that bug with the "mission" button. At this time, it also included the mini-map, etc. but then, they "half" fixed it. I agree, that's really annoying. Especially for Blitzer at Vanaduke.
