Well, I had a flash of inspiration, which seems to have cured the problem. When I first installed the projector I had to hard reset it each screening by removing the power cord to fix an HDMI issue I was having. PD provided a firmware fix for this and I've not had to unplug the projector for the past 5 months. So I tried the hard reset this morning and it worked - everything looks ok now. I guess the firmware got "confused" somehow and only a hard reset would fix.

Weclome back to our scheduled programme! laugh
