Street Atlas 6.0 fixed in Classic! Since 10.2 (my entry into OSX), Street Atlas failed to show route directions on screen, a valuable feature which I had assumed gone forever. Especially after buying a PowerBook that cannot boot OS9. Hooray! One of my most valuable programs just became more functional!
And as many have pointed out, Safari is working better. I was about to abandon it. I'm still hoping that Tiger will further improve its performance - it still has more beach balls than when original despite utilizing all the maintenance tips I've read here.
I'm pretty happy!
