Of course it will give only positive values.
What do you expect :} you even prevent mouse cursor from moving outside client area (if I'm right .. with ClipCursor)
You'll get negative values only when you'll use SetCapture AND u r holding mouse button while moving AND mouse cursor is outside active window area

No I mean, a less value than the center of the application, I called that a negativ value or a jmp less.
Nevermind, I found the mistake.
