What in the world do you mean by an "unmodified PC"? And why would anyone have one and why would it matter? Are you claiming that only PC's that are wide open to infection are allowed at this site? And what in the world is an "unmodified" browser? I have never heard of such a thing. It would be dangerous to run one like that and again are you claiming that only browsers that are wide open to infection are allowed here? Geez.
This problem only began AFTER all the changes Justin made at this site. I've been here since 2001 and had no problems like this until Justin made so many change ssome of which are for the worse IMO. I've never used a "unmodified PC" (although I don't really know what that could be ...but I can't imagine anyone using one as even just adding an antivirus program modifies the PC) and had no problems with Postlist/all which has been my home page on all browsers since I joined in 2001 so I can't see how it could be my browsers as the culprit. The culprit has something to do with all these changes which make it much more difficult to use this site because of all the extra clicks necessary now and the fact that we are supposed to use just a few words in replies in forums since the normal reply box is now relegated to second class choice. There are some good changes here though as well as the not so good ones.
