I took the leap during the night. Erase and intall. I'm mostly happy, but there are some bugs (so far) I woundered if anybody else have experienced: (Haven't found any in this forum...) 1. Mail Help says Mail 2.0 should be able to nest smart mailboxes. Either in regular- or in other smart -. My Mail 2.0 can NOT. So all my smart mailboxes just stays on top of the "Mailboxes" hierarchy and will therefore use up all space quickly. (I can use "in Mailbox" as a criteria in a smart mailbox, but thats not what I'm looking for...) 2. Customizing date formats (now has a bad UI - in the first place...) zapps back to default if I make too many changes. It can accept me changing the short dat, but if I keep on changing medium, long... the short changes back by itself. 3. There is no customizing opportunity for number formats anymore !!!!! 4. I don't trust the color picker in the systems "Colors" anymore... It seems to pick a slightly darker color. 5. For those who use Filemaker 6.0 v4: Ctrl + arrows for next/previous record do not work anymore (on a norwegian keyboard anyway...) I have a Pb G4 1GHz 17" Anybody...?
