Query: IntelliMouse Explorer 2.0 Will Not Work Properly With Pad

I have a wireless Microsoft IntelliMouse Explorer 2.0 optical mouse. The mouse pointer will not move properly with this mouse pad. I will slide the mouse down 2 inches and the pointer wont budge. I tested the mouse pad I'm replacing and the mouse pointer moves fine so it's not the batteries or the wireless connection. The surface of the mouse pad must not be reflective enough. Or maybe it's the blue color?
