Well, just to raise this issue again.....it had gone pretty quiet. Driving my car out of the garage yesterday morning for the trip to the Factory for the TM Tour, I noticed the screen had cracked overnight! A crack from the top left of the screen diagonally down for about 6 inches. The crack developed down to the bottom of the screen whilst parked at Morgan during the morning. Very strange that a screen should last a couple of years and then suddenly fail. Of course the car is now out of warranty so it looks like an insurance claim. It does pain me though that the insurance company should foot the bill for an obvious Morgan problem.
I mentioned it at the factory to be told that their new 4/4 hire car screen had cracked within a week! So the problem still exists....even on the new cars with the alloy screen supports.
