This is all on a page script not an activity script. So not sure what you mean by moving this to a page script. Not sure I understand how the widget be NULL if not found when all the widgets are on the page. To answer one of the first question, either every thing works or nothing works. So it makes scene if the first command hangs up then every thing else does not run. So the first line may be the problem then. You are correct it for a New Denon receiver via my GC device RS232 device. I also had the same issue with the old receiver too. So I wonder if there is some thing going on with the GC code you helped out with. Also seems to be more of an issue when ran from the remote. Have not experienced this on the simulator.
