Dear all,

while travelling in Germany, I bought a Sunnyline "Mini RF Optical Mouse 'freestyle RF'". Unfortunately, the mouse has problems: When the mouse is lifted a bit off the surface, the mouse pointer zig-zags towards the lower righthand corner of the screen. It also seems to me that when sliding the mouse on the surface, the pointer moves right / down more readily than left / up.

I've opened the mouse and cleaned the plastic prism / lens etc. stuff, and also widened the hole underneath the lens, but nothing has even made a difference.

I realize that this is not a Linux specific problem, but perhaps, someone here had a similar experience and can suggest a fix for this problem.

Best regards, Jan
