If that fails, walk him through the other steps in Solving Technical Issues . Really. You guys already know what the problem is. Why do you keep trying to blame it on extensions? It's a process of eliminating excess variables from the equation. If you're 99% sure someone has cancer, you still try to eliminate other options before you diagnose them. It's the empirical way. Admittedly, if this is a repeating issue (and I don't know if it is the case), then I have to agree that it's probably silly to keep it asking the same questions, but if he had something installed on his PC that disrupted the javascripts on the server, it's better to get that out of the way than to begin an investigation on what might be wrong with a site function! Out of curiosity Phil, what IS causing the issue? I don't really want this to happen again. I've learned my lesson, and I'm using both fog of war and dynamic lighting now...
