Hi Al,
Yes in S1.60 we introduced a new piece of software to send data the display on the front of the unit, it uses far fewer CPU resources then the previous version; however because its had to be rewritten from the ground up we are not at all surprised that some customers would experience problems with it. Are you running S1.60 or S1.65 (released today, but has been posted on the forums for a week or two now)?
Cheers,
Chris
