New Post: Order History logging out user

I'm running NBStore 2.3.8 on DNN 7.2.0

If I log on to the website, then go to my Order History page, I'm logged out, and have to log back in again.

If I logon on the Order History page, then go elsewhere (store admin), then come back to Order History, I'm still logged in.

Not a big issue, but probably not working as designed.
