I think youve made similar arguments before Max; where all of your evidence exists by being reliant on itself, but doesnt actually make any sense when you look at the big picture haha.
A). can be explained by me trying to open two windows at once: however instead of opening a link on the forum into a new window, i opened a new window first and then linked it to the forum from my favourites. Unfortuantely for me, the link was to the sign in page which i have configured to log in automatically, rather than to the forum homepage, which in turn logged me in twice without my realising it , and generating the IP error, in accesseing threads.
B). With a simple firewall for example zonealarm, Internet explorer 6 performs just as stably and effectively as any other browser, and it has the advantage of being developed in conjuction with the operating system native to it, increasing effieciency of the browser itself as it is programmed by those who understand the complexity and workings of the OS.
C). Max's personal computer uses Windows XP.
