Do you have any other systems "talking" to the Escient?
We have had a similar sounding issue.. and I think it may be due to the fact that a Niles ICS system is communicating to the Escient (via RS232) and there may be some conflict here... or perhaps the Escient is being direct to a new song/genre etc by the ICS and the web interface is "losing" touch with what is happening.
Grasping at straws... so keep me posted.
...couple a thumb tacks and a stick of double sided tape should hold this baby up...
