I have a bunch of small issues with osx leopard right now and I'm thinking of reformatting with a fresh start. Some of the issues I'm having is when I save a file to desktop, it appears in a corner of my screen or a random spot. In photoshop cs3, whenever I zoom in with my mouth scroll wheel, the program lags for about 4 seconds. These are just a few of the minor quirks. Would it be better to reinstall every application manually or would using a time machine backup be just as good?
