I am countering this problem:

Inside the Admin Section >> "Vouchers/Coupons" >> "Coupon Admin" page
Status drop down list always showing by default *Active Coupons. *When I
select any other item from the list I found myself logged out and starting
from Admin Login again..! asking for my admin login and password!?
Can any one help me
David replied to asking the following:-This is a session maintenance issue.
What version of the software are you running?
Are your cookies enabled?
What are the configuration values for your sessions? (Admin -> Configuration -> Sessions)
And the following was my answer:-Software Version: CRE Loaded v 6.2[13.1 (SP1)]
Sessions
Title Value
Session Directory /home/sabayast/public_html/cart/tmp
Force Cookie Use False
Check SSL Session ID True
Check User Agent False

Prevent Spider Sessions True
Recreate Session False
I hope someone can help in this issue!
Thank you
