I am using IE9 and every time I log on, except for when I check auto logon, I have too do it twice. I can take a screen shot of the screen after the first attempt if I need too. It says something on the screen after the 2nd attempt to log on about Vbulletin message but I can't remember because its 5 am and I have been up most of the night. After the 2nd attempt it goes to the forum listing page as normal.
