Aha might have sorted the problem...I think

I borrowed hubbys mouse mat (the special one he uses for gaming) and that seems to work for my optical mouse. So I think that could be the problem, heres hoping  I just need one of those mats (with the rougher surface) At the moment I either use the dining table with my naff mouse mat or my laptop table without a mat if Im watching a movie or something.

If this does sort it, I have a fair few good ideas for my childrens clothes. I also promised my daughter I would make her a mario T-Shirt for her Sim. (she loves Super mario Kart, and is so much better than me)
I also thought a few summer tops for ladies would be great, as our UK weather is perking up a little (may be Im speaking too soon on that one) :)
