I have had a few FC's on my Milestone (Brazil version on 2.1), but those are not a big deal to me.
I do have one small issue that irritates me to no end. When you place the phone in the Motorola Car Dock, you get the car dock screen with an icon to go to the home screen. This takes you to the original home screen and not Launcher Pro. Hitting the home button on the phone takes you back to the car dock screen, so there is no way to get to the Laucher Pro home screen when using the car dock, even if you have Launcher Pro set up as the default screen. This means I have to keep both the original home screen and Launcher Pro set up how I would like them.
I guess I could look at it this way, I can set up the original home screen how I would want it in the car dock and have Launcher Pro set up how I would normally want it. If you can't fix it - feature it....
