an 'issue ' with 'previewing' postings; am logged IN; I add an entry with a link to another thread; I click ON preview; that part is OK; I then click on the link such as http://www.bleepingcomputer.com/forums/forum9.html

I have added to check for validity; and find myself logged out

has Admin any ideas? this has happened repeatedly ,even on my test thread

whist composing THIS I am AGAIN logged out and have had to log IN again to post this

That happened to me quite some time ago, and clearing browser cache and cookies and doing a machine restart solved the problem. Unfortunately, I never did find what caused the issue in the first place. So I don't have an answer for that question. I chalked it up to some sort of browser anomaly.

I hope if you don't find the answer, that what I suggest, will work for you.
