I've found the problem, I think, or at least forced a fix. Something was in some way seems to have been poisoning the CSS settings in Omniweb in a way that even deleting preferences and OW itself and even going to a new Mac OS X user wasn't curing. I don't know if there's some sort of hidden file that OW uses to hold CSS information, but on a long shot I tried setting the Style Sheet setting to a local file and the sites then loaded without problem. Setting back to "None" still works, even after quitting and reloading OW. It may be that the problem setting is in the application bundle but that just reloading the OW app just caused it to be poisoned again.

So there seems to be some sort of subtle bug in OW's style sheets handling that allows the setting to be poisoned in a way that persists through deletion of the various application support and preference files. Perhaps that will give your developers a clue.

I'll confirm once I have a chance to try the same thing on my home system.

Regards.
