Hi. I read the thread "Session return", but unfortunately it seems to me I still have some problems with session expiration. I use Firefox browser and i open some pages simultaneous usually, but sometimes some pages don't show the left frame with menu items, instead of the menu i can see a Login link. It's strange cos the main frame looks like it knows me, I mean allegedly like after successful authorization. Is it bug or should i better use one page only? :)
