When I log in and write a long post, when I try to submit the post I get a new dialog to log in. So I put my name an password and click the button. But then I get an error message that tells me that I logged in since the last time or something to that effect. I says that I should click the back button to return to the previous page. When I click only once the back button it does not take me to the previous page. When I click twice the back button, it does send me back to the previous page but all I see is the quote I was answering to and not the text I typed. I have lost many long posts this way. I am using Vista and IE8. I'll try to recreate this problem again and this time take note of the exact text of the error messages. It looks to me that some part of the forum's program thinks that I am logged-in while another part (the one that prompts me to log-in again) thinks I am logged-out. Has anybody else experienced this frustrating problem?
