I've been having ongoing issues Ice that I reported to Axiom webmaster some time ago. Deleting browser history (temp files, cookies, also "uncheck" preserve sites) helps sometimes, but in my case it didn't. There was some caching problem on the server end, which they seemed to have resolved until today.
Today I am able to login fine, but as soon as I click on one of the thread sections, for ex Home Theater, it is like I'm logged off all over again, doesn't stick.
This is the only UBB forum I have issues with, and I am a member of many. I am on IE 9 now.
