Support site logs me out

I’m having trouble with your support site itself

When I log into it using IE and Chrome at the same time I get repeatedly logged out of the site. Is this a bug with your support site? For example I typed this message in text editor so that I could quickly paste the text and create a ticket. If I try to sit down and type out the ticket I would have been logged out of the site, by the site, before I could finish typing the ticket out.
