I don't know when it starts, but I'll be running my powerbook with Panther on it for a while and eventually my fonts will go screwy. In particular the spacing between letters will start to be off. It'll be especially noticeable when I highlight text. Sometimes the text I've highlighted will only mostly be selected. And almost always once this starts a huge spacer gap will appear between selected text and text next to it that's not selected. If I reboot it'll stop, for a long while. I just rebooted again recently so it's not happening now, or I'd post a screenshot. I don't think I've modified my default font for Safari or my operating system. Has anyone else heard/seen this? joe.
