The intermittent thing is whats baffeled me too. I've tried to find some pattern to it, but I haven't been able to.

Also, I used to have it set up to set 3 cookies, one for each variable, and it would set different cookies at different times. Sometimes the name cookie would be saved, some times one date or the other, sometimes 2 cookies, sometimes none, and rarely all 3.

I'll try setting a path and see if that helps. I only have access to mac's at work so I won't be able to test it until then.

I should also note that the same problem occures in OS 9 and OS X.
