I panicked this morning when I logged in as a user to my GMail installation and it kept giving me "expired/invalid session" errors. I tried a couple of different domains and user accounts and all gave the same results. Then I switched to another browser and it worked fine.

I got the errors with the latest beta of Safari. Obviously it has some kind of problem related to sessions and/or cookies. Folks might want to warn users that are using Safari about this problem since they may think it is a problem related to GMail.

I've sent a bug report to Apple outlining the issue.

cheers,
