Thanks Peter
The diagnostic showed that it was a problem with the desk, so at least I wasn't going mad last night! After repeated hard pressing of the beamshape button I have got it to function now. I guess my concern is that it may come back and haunt me at a later date, so not sure whether to suggest you go ahead and replace the desk now, or cross my fingers and hope that the button will continue to work fine now? I need to get it programmed and used ASAP, so can't really be without it. What do you recommend?
