If you set the Vista desktop (i.e. the big window behind all other windows) to Auto Arrange then the icons on your desktop will flow down and, if you have enough of them, in columns towards the right. Make sure there are enough files on your desktop that you have multiple columns. Two columns is enough but three will really make the problem stand ...

I found this interesting. What's with all these some notify boxes are rounded and some are square? Also one thing is that rounded notifyboxes are broken in some cases. Like with that audionotify box in 1024x768.
