I've had problems with the board bumping me out too. Sometimes I've had to log in 2 or 3 times in an hour - Sometimes, in 10 minutes. Other times, it keeps me logged in. I've also had problems with clicking on links in posts or going from one forum to another. There's a certain sequence I have to follow: can't use the "back" button, can't go to the
"board index" from the two buttons on the top and bottom, I have to use the bottom right forum index and then "Go", every time. I also copy every reply because the "submit" has a tendency to bump me out too.
I've asked about it too, but no one can figure it out.
