Thanks. I have also tried looking in the config files for the session info and those are both 'db' and checking the cache file which is set at 777. I've backed up and deleted and re-installed the db several times. I've called the host (hostmonster). I'm really just at a loss. And it never seems to happen with people using Firefox or Safari which is odd.

I have thought about updating to 1.3.9h, but have been fearful. This was my first install of zen cart and I've messed around with the files here and there sort of a lot (without keeping track of everything I've done and/or putting the new files in a separate override folder).

I guess it'd just take time after I updated to go back in and re-do all my little tweaks. Maybe I should get over this fear and dive in.

In the meantime if you think of anything that could cause this issue let me know.
