Hiya Digifan
Glad to hear you're back home, and hope the recovery goes well.
Have you tried using
Fire instead of the ICQ client? It's like an aggregator for chat. You can access your icq, aim, yahoo, irc, jabber, msn, and google talk accounts from one interface. Scrollable histories for all accounts and services. Searchable chat logs. Tabbed interface. Themes. I haven't used any of the individual clients for years.
If you give it a try and have any trouble configuring it, just let me know and I'll be glad to help.
