Airport Disks still don't always show up in the Sidebar under the Router name. I still have to restart in order to get full access to both my Airport Disks. When opening folders through the Finder, I still have to click off the folder then double click back on to continue surfing through the folder. If I don't, then no matter how much I double click on the folder, file or whatever, it doesn't open. I have to click off it, then double click again. In general, double clicking just isn't very responsive at all. Ejecting connected external hard drives, I still cannot eject certain things, such as my Time Machine hard drive. Still no Bluetooth support in Address Book. That's things just off the top of my head. There is a few other problems I can't remember.
