>I find that all cross-thread links behave that way. They're OK when I view them in threaded mode, and the first page is OK in flat mode, but if I click another page number or Show All in flat mode, I go to a completely different thread as you found. This applies whether the link has been referred to with showflat.pl or showthreaded.pl in the url.

It may be my computer. It seems to be fine on the threads that are on the first couple of pages in each section, after that, they all go loopy. If I bring a thread to the front it sorts itself out (for me, anyway). Are you saying that you still cannot view this thread without it tangling up?
