Trying to stay ahead of my clients, so I took the plunge, bought some Vista Business licenses, and installed it last week on a shiny new Dell computer with a nice empty hard drive.
Some of the security enhancements are just as annoying as promised - the dialog boxes popped up by User Account Control really are intolerable, no matter how good the reasons are for them.
MC12 was one of several programs that just refused to be happy until I turned down some of the default security settings. It wouldn't start without a confirming dialog box about whether I really liked the program until I turned off User Account Control. More importantly, it wouldn't hold onto any customized settings until I gave my account local administrator privileges. I had other reasons to do both of those things also, so it's running beautifully and smoothly now, but January 30 is right around the corner if there are things that can be retooled.
If MC12 is minimized while it's on "Playing Now," some Vista previews don't display MC12 correctly - thumbnails in Alt-Tab and from the taskbar are blank. One of the prettiest visual tricks in Windows Vista is the angled 3D display of open windows - it might have some fancy name but the button is labeled "Switch between windows." If MC12 is minimized while it's on "Playing Now," then a space is made for it in that 3d angled group, but MC12 is invisible. Hmm.
For what it's worth . . .
