Using Xorg-7.5-lib now, which seems to satisfy dillo, but I still can't log in to the forums here. I just get a yellow screen.
I've allowed cookies in dillo, and the console shows various traffic relating to cookies, but nothing but solid yellow in the dillo html pane.
"Reload" at this point causes dillo to immediately crash, printing "Segmentation fault" to the console. Bummer dude.
