Yeah, he's rebooted (it's just on his PC) and I made sure no pvxwin32 processes were running. I also rebulit the GL files (hoping to have it hang on one of them) and even pulled up each one in DFDM (again, hoping it would squawk). I'm afraid it's a field somewhere and I have no idea where and the TRSG hasn't helped (I checked GL0 and GLW).
