I've been using my own icons in Logic 6-7.2 for ages, could never get Logic to see the Library/App support/Logic/image/icon thing, so I just selected the Program, right moused to find Resources and found/substituted the icons that way. About 128*128 pixel size, I've never found it necessary to be that accurate, just make them reasonably small (why waste graphics power?) and give em all numbers. Ive got photos of my musician friends, scenary, neked ladies, dinosaurs, spiders etc - much more fun than the than original icons. Logic doesn't seem to mind at all - in fact I think I've cheered it up a bit... Russell Canberra Australia
