Everything still working OK for me.
Sometimes the cookies get corrupted. IE5 stores cookies not only in the windows/temporary internet files folder but also in your windows/profiles/cookies and windows/profiles/ie5/content folders (and maybe some other places too!), eg.
[email protected] and
[email protected].
Do a search for all the places your weblyer or forumcgi cookies are located and make sure you delete them all (at least your flyer talk ones.
Then go back to Flyertalk, log in, change preferences and make sure you check the radio button for allow it to store for one year (some of your's may have expired?, more than one year?, or just it can't calculate what one year is with the year rollover?) Who knows.
Good luck though. I almost tore my hair out last year when this happened. No problems since other than the cookies occasionally getting corrupted, having to delete manually and reset.
