Mike,
You're probably on to something with the remote. Unfortunately, the iFly was in the plane when I purchased it and I did not get the remote - did not know to ask at the time. It is still perfectly functional at this time, but gives random fits with button selection. The fact is CS said when the screen gets to the point of not being able to be calibrated, there is nothing that can be done except replace the screen. I was just caught off guard by this from a relatively young, $750 piece of equipment. Who knows, perhaps it will not get worse and will remain in its current state (useable, but at times very frustrating) indefinitely.
