I use OF 3.6.2 and IM-getway 1.2.4d. As a client - Miranda 0.7. Sometimes when other icq users writing to our users, messages are not deliver. All users are have online status in icq. If reboot miranda, messages will delivered, like offline messages.
Can’t suggest anything. Just wanted to let you know that with the same setup (only using Spark) i dont see such problems. On the other side my ICQ contacts are using different clients (Miranda, QIP, ICQ original client, etc.)
