Save for web is grayed out (Not functioning)

So glad that you worked it out.

It is essential that Adobe applications are NOT moved from where they are installed by default.

Put an Alias on your Desktop, or in your Dock, if you wish; but NEVER move the Application itself!

I switched from PC to Mac because I wanted to be /less/ frustrated.

If you move, rename or create subfolders in the default installation location of CS3, you will be frustrated to the point of despair. Just don't.

CS3 is a whole new game in that respect.
