Mr. Ferri, I've started a thread of discussion about that a couple of weeks ago, but I didn't have a satisfying answer. However, I've proposed a fix which seems to work. I think I should go further with Motorola about that problem. Can you take a look at it and tell me if it helps? Also, can you tell me which processor mask you are running on?
