I've seen similar Horde behavior over a stressed link (i.e. when other  
applications are flooding the server uplink). Maybe it's some  
browser-side (AJAX) code that's waiting only a (too) short time? In my  
case, we're talking about network-added delays of a few seconds (less  
than 10).

Just my 2 cents.
