Whenever I try to use my WASD keys or dragging to move the screen around, my SCM2 freezes. (Scrolling works perfectly without problems.)
I downloaded the 0.8.1 version, and reinstalled it, but the it still froze. Sometimes if I'm lucky it unfreezes after about 10 seconds but most of the time, I have to use task manager to close it.

So, is there anyway to resolve this?

May I ask, do you use windows 8?

No, I use Windows 7.
