Random Logging Out
 

I know this as a computer setting on the machine, but any ideas would be great.

I created a phpwebsite 1.6.2 site for my in-laws, all works well from my laptop. When I was attempting to show them how to update/edit the site on their computer it would randomly log me out of the system.

I tried multiple times in both IE and Firefox doing various actions and it would log me out sometimes after 1 minute others after 5 or so. They are running Windows Vista.

Any ideas would be appreciated.
