Thanks for your suggestion, Michael. I'm running Horde_Core 2.13.0  
which was upgraded when I ran 'pear upgrade -a -B horde/webmail' I  
believe.

I believe that I've got the cache and session handlers set up properly  
using the recommended Horde file system types. My config is below,  
perhaps you could tell me where I'm going wrong with it?

Many thanks for your time on this,

Tim
