We have extremely frustrated admins who are logging in and then within minutes and a few clicks through navigation getting directed right back to the login screen.  Basically they are getting logged out.  Using v 1.0.8 of Joomla. 

We have approximately 5-7 admins who are using this site, and they are all having this issue.  I can't find any real consistancy, sometimes it happens in two to three clicks, sometimes we get further.

We thought it was a superadmin rule that you could only have one Superadmin logged in at one time, so we created new accounts and gave them only admin rights, deleting all the superadmins but one. 

I checked the forums and although I found stuff on Mambo didn't find any specific Joomla issues, sorry if I missed it.  Do you guys know what might be causing this?  Any Ideas?

Thank you in advance for your time and help
