I have a problem: I can login all right, but I am being logged out literally each minute, which isn't enough time for me to write any of my posts! I write them and then submit, and then have to login again and when I do the paragraphs I've written are gone; so I've taken to copying my posts since I know I'll be logged out before I finish typing a few sentences and then pasting it into the Post Reply box that appears after I click Submit and have to login again.
It's very annoying, and I don't know what to do.
I have Internet Explorer, and would click the automatic login box except this is a shared computer and my brother is a known hacker and troublemaker so I wouldn't want him messing up my account or posting any profane things pretending to be me (we only have one user account on this old PC).

That sounds a right pain. My advice? Keep logged in. Tie up your brother and then you'll have no worries. 
Seriously though I hope you can get it fixed.
