Well, I'm giving up on TimeMachine.  At first I thought it was just me having problems, but the other newly "Leopardized" machine here is failing with "error #11" while trying to use TimeMachine.  At least his machine doesn't have to be physically powered off and back on to recover from it.  Possible that we have two different sources for our failures.  At this point in time, I'm leaning towards my failure as being something having to do with either FireWire support in Leopard, or my external drive unit itself (the OTHER machine here with problems is using a known good (at least up until the upgrade!) drive unit).  Even trying to zero the drive out with Disk Utility fails (after running for about 20 minutes).  Doesn't exactly match up with the TimeMachine failures though...  Either way, I'm giving up on my machine now.  External drive goes back into storage, and TimeMachine is getting shut off.

After more living with it, the translucent menus are getting real annoying.  Grayed out text blends into my windows that are in the background.  Also a little annoyed with the new filesystem viewer.  Looks very cool when you can get what you want on the screen.  Unfortunately, I have TONS of folders on my NAS device, and it seems to randomly choose which ones to pre-open.  It never guesses right...  Makes it take a lot longer to get where I want to go when I have to either go through the list closing folders to make enough room to see what I'm looking for, or scroll all over the place in the somewhat smaller window that's available with that view!

I think I'll shut the Mac down for the day, before I fling it out a window, and go back to my nice comfortable SunRay and Solaris desktop for now.  :-)
