Thanks syd,

I will take my Q50 and NC with me to work tomorrow and see what happens.

I really hope this is not a hardware issue. What is odd though, is their are very few of us on this board that I see own both the Q50 and NC, and aside from the installers, it appears most of the rest of us are sharing the same issue.

Is it possible that installers are running an updated hardware/software version that the rest of us do not have access to yet, which may have corrected the issue?

Well, we shall see....

Mark
