I tried to put error -2004 into the utilitie "Mac Errors" but it wouldn't take the reference. I suspect that the problem is that you don't have enough
Ram as I have had the same sort of problem when I bought my CD 300e and had to by another 8 megs of Ram because the CD's were running to slow . Its a real pain in the butt when that happens!
As to the 'Quantum Leap' part of your letter I haven't heard of of anything but when I do I'll write into Mac Format to tell you the news.
If you or anyone else wants to write to me my adress is above.
