ZxChat not displaying every messages

Hi all,

we've got Zcs 8.6 installed on Utuntu 14, and Zextras modules 2.4.12 only for ZXChat (1.36)

we've got a problem when some users are in invisible or occupied status, some messages won't appear, or will appear only in the tchat folder.

I know we've got few updates to do, but i haven't seen any bugfix that concerned this.

Is it a known bug? or can you help me tracking the error?

Regards.

Jrm.
