LinPopUp

Dear All, I have samba installed and trying to get it working between Suse 8.2 on my athlon 1600+ desktop and my husband's win 98 desktop. That is somewhat working, but my first concern is LinPopUp. I have Real popup installed on his win98 and it works fine receiving my LinPopUp messages but my LinPopUp will not receive any messages from him. I have looked into some archives about this and others have had this problem as well but I have not found an answer to it yet. Does anyone know how to get it working with sending and receiving? It sends just fine but will not receive. I followed the instructions for editing the smb.conf for it but do not know what else to do. Any help will be greatly appreciated. Thanks, Marcia
