I'd be happy to help you out, but first I need some more info on your system.
What CPU and OS are you using? Do you have a graphics card?
Do you use DOpus (WBR), FBlit, VisualPrefs, MCP or any other similar programs?
Sorry I haven't read the amigaworld guide so I can't comment on how good that is.
What is Birdie currently (not) doing? Are you using Birdie 2000?
