Apple Users

A default setting, so that may be why it went back.

Note there is an option for 'hot keys' which would begin that application when you least expect it.

I've made changes to my Universal Access option, you may have triggered one of those.

I've disabled them, along with Front Row.

If I trigger something I don't want, or the application is overworked I guess, such as Icon Preview not working, Restart returns the default settings.

I made icons for all my folders, as well, through the Finder's File option, Get Info. That way I don't even have to read the label, just click on the picture, image or screen shot I selected as for video, photographs and other collections.

This helps people who can't read, but can use a mouse and I find it's faster for me as well. Good luck with the MacPro. How large is the hard drive on it?

I'm using an older iMac with 250g and have a older laptop with 250g that I keep for the day when the iMac crashes. I found the laptop hard to use.
