I ran into a usability fail that has to exist from windows 3.1.
Windows arranges it’s icons/shortcuts/files on desktop column by column. But if you select them with SHIFT (multiple select), it selects them line by line :).
If you arrange icons by type and you want to delete the pictures, you cannot do that by selecting them with SHIFT from first to last.
Since I use windows for ages and not realized this until now, i don’t think it bothers people, but still… interesting find.
