does somebody know how to solve the problem when IE is losing the session all the time? ... when I open a link in a new window or sometimes also when I open e.g. the "slot window" for an airport I get a message telling me, that my session timed out... I know that's a problem of my browser... and I also know that this happens sometimes since the IE8 got released... but I didn't find a good solution how to fix the behaviour... does someone know how this can be fixed?
I am pretty sure those session variables are server side and not client side.
Try logout-clear cookies-login. Might help, since there were some changes with the new forum. Make sure cookies are allowed too (should already be, as otherwise you could not login at all...)
