Media Server :: "onDisconnect" Not Called Up With MS Internet Explorer Users

We are using Flash media server 3.5 with Windows. We have deconnection problems with visitors using Microsoft Internet Explorer (to be fully confirmed but we are nearly 100% sure) and in chat rooms; there they wait for their turn to speak to an online consultant, sometimes this waiting list can be 10 to 15 strong. Normally, when a client is automatically disconnected from a session, whatever the reason it is the ˜onDisconnect which is called up. Sometimes and with MS Internet Explorer this is not the case : the visitor or user is not anymore present in the chat room, he has quit or he got his interview with the consultant but ˜onDisconnect™ is not launched.

This causes unexpected problems like one or several people in the waiting list being kicked out of the ˜room all of a sudden without explanation for the user. Normally our consultants are on the air for one hour; after this time frame another consultant comes into the same chat room and normally he gets the remaining waiting list from the previous consultant and the previous hour of chat. Sometimes but often, the new consultant coming in sees the first one or the first two of the wainting list kicked out of the list : he then takes the second or third one in the old waiting list.
