No pop up on offlines messages

Hi guys,

using ZxChat zimlet 11.09 with zextras 2.10.2 on my Zimbra 8.7.11 i'm having troubles with offline messages.

When some one write a message to an offline buddy, there is no notif on connexion. Message appears when we open the chat box from the contact. This causes a lot of failed messages, and unhappy users.

Is this a known issue? and something to deal with it?

thanks!
