Thanks for the thoughts - When I was able to leave the room on a break, I took the battery out and have soft reset since that time. I didn't try to soft reset while I was in there because I didn't want to draw any more attention than I thought was being drawn to the buzzing already occurring.

I'll have to test it out the next time I get a call.

I haven't done any reg hacks, though I have Quick Menu, Ultimate Launcher and HTC Home Customizer - I can't imagine any of those progs being the culprit.

Thanks again,
MK
