Thanks in Advance, Larry Gray Just an advice: if you want your problem solved, do not reply to 1 year old thread. Make new instead with detailed information about your problem. Lots of things changed during 1 year, even the software versions and updates and I think you get faster help on new thread.
	Best regards, Darius
