Thanks for the reply back,
I saw it just as I was logging in to post that I read in another forum ( LCD displays ) some people with issues where the LCD drew too much current for the USB to adequately power both the Arduino and the LCD.
Turns out this was it, Added a 10.5 Volt supply to the DC input and things are working perfectly now.
It was a sainsmart due/shield/TFT combo that I grabbed. Wanted to mess with something dirt cheap before I bought the real thing. I haven't been using their libraries though, went straight to the source for UTFT and UTOUCH and those seem to be working as I'd expect.
Anyway, Thanks again for the response.
