This may be a first, in my entire blogging history — me saying something bad about anything Apple.
Time Machine is an excellent part of Mac OS Leopard. It has saved my rear many times. (This is a backup feature whereby it transparently backs up your internal hard drive to an external drive, so that you can grab a file you deleted a month ago — or get yesterday’s version of that file you changed a lot. Or go into your email program and retrieve that email you deleted.)
The bad thing? When you are done retrieving that file, the way to exit Time Machine and return to normal life is by hitting the “Cancel” button. That’s stupid. It sounds like you will undo the file retrieval — when you just want to exit.
Apple: change the wording to “Exit” please.
