imp 2.3 session problems. Mixing with old imp 2.2.3 install.

[Todd Mortensen]

I have setup imp version 2.3 as per the docs/INSTALL file.  

On the same webserver I have the old 2.2.3 version setup, It is currently
being used in production.  
When I login to the new install via imap it lets me in ok.  
But I don't see my mail each time.  sometimes I see someone else's mail.
Its like I am seeing bleed through from the other installation.  

I am using a different horde database for each via mysql.  I have the
session name different between the two.  

Has anyone else seen this behavior ?

Thanks.
