Me too...
It looks like the TS is seeing a permanent press in the bottom RH corner.
I've tried taking it apart and cleaning around the TS, checking all the connections and updating the software, but it still does it. I reckon it must be a hardware problem with the TS itself.
I'm plucking up courage to call the Tomtom helpline - but I hate dealing with the things!
