Hi Carlo- sorry I have no solution for this, and I tried many different things. I had to turn the pad off and use a mouse!
Now I have a different problem – I decided to load Linux on my Jumper to have a machine using this OS. It works well except that the sound card won’t work :). I read that this is an issue with Linux machines using the Intel Z8300 processor, and so far there is no solution for that either!
