I love Tiger, and I generally don't have any real issues with Finder either, except that when I have multiple external drives mounted, they rearrange themselves seemingly at random every time I (infrequently) restart my machine. It's not a major issue, but it's slightly irritating, and I would like to stick them in one place and make them stay there.
Any ideas on how to stop this happening? In case it makes any difference, I have my desktop View Options set to "Snap to grid".
