Hi Fred, I don't have any direct answers to your questions. However I use an iBook 600 and I use similar software and it all works very well. However I access the Internet via my telephone lines. I also use Tiger OS-X.4.11 with Disc Warrior 3.03 and it still works beautifully. DW version 3.03 is the latest version of this software. My suggestion would be to set up another "account" on your Mac as if you were setting it up for a new user. I would then reinstall all the software that are causing you problems to see if they connect properly to your satellite hook-up. I recently had problems with my keyboard. The numeric side had stopped working. I set up another account and now it all works perfectly in that account. However I still haven't figured out what is wrong with the other account, but it saved me buying a new keyboard. Now I have to get my brain working to repair the KB issue on my home base account.
