I am still working on trying to figure out the issue with the segfault on the other machine.

Have you been able to wring any new information out of it?

Not yet, but I have not had much time either. Still thinking about a plan of attack. Not sure if I mentioned it, but Jorge had mentioned trying a different compiler, which I did (rebuilt both FLTK & Dillo 1.3) with gcc 4.4, 4.5, _and_ 4.6. Nothing different. Tried building FLTK2 on the problem machine, and could not get a clean compile. This interests me, as I have no problem building it on my desktop. I am going to look into that more.
