Nope. You're trapped. You have to live your whole life with Finder asking if it shall prepare the CDs you insert for burning
Uhm, I'm not sure, but I think a very handy shareware util called "TinkerTool" might be able to do that. Search for it on http://www.versiontracker.com/macosx
Yeah, I saw that seconds after I posted the message... So that's much much better! But, still... I usually go for a blank CD first instead of launching Toast.
I'll look for the tinker tool and see if that does anything once I get to my studio (where my Mac is - on a PeeCee at home! And don't get me started - I want to replace it with the new iMac so BAD! heh).
