Thanks, I will take a second look.
I tend to customize things heavily because I spend a lot of time using them. This Mac Pro not so much. However, I've always had a clear dock since 10.2.8 and this is one of a few things about Mav that bothers me. The other being that Apple killed off labels. We use labels at work to designate what kind of ads we're working with. Now it's these little hard to see balls that because of the way Finder windows work now disappear when I expand the windows.
And that's another issue. Since Lion, it's impossible to manuever a window down in size to anything like you can with Leopard.
And don't even get me started on the wacky SMB2 and ACL permissions crap that Mavericks is pulling over on our new Win 2012 server!
I've been forced to disable Quicklook because it in combination with Get Info and the Finder has the Finder holding folder and files open for a set period of time even after you close them. That makes it impossible to rename folders and files until the hold time is up! And now I have to connect using CIFS in order to force a connection at SMB1!
