Automatic look and feel undo doesn't seem to work

Hello,

First, I love the new look and feel your team gave us in 6.0. I can't imagine the tremendous amount of work everyone put in!

I wanted to play with the automatic look and feel of the site. I used a custom skin in v5, but wanted to see what your tool would come up with. I uploaded the first image (see attached: first.png). Because of the transparent background, the system adjusted to your default, this looked great, so I wanted to keep it. Because this is our test system, I need to get the second image (see attached: second.png) as the logo. When I did this, the automatic look and feel kicked in and created a nice schema, but I liked the other one better. So I clicked "Undo" and it didn't go back to the blue schema.

So steps to reproduce:
1. Go to Admin -> User Interface -> Look and Feel
2. Upload first.png.
3. Navigate to another part of the site. I did this to make sure the schema actually did save.
4. Go back to Admin -> User Interface -> Look and Feel.
5. Upload second.png
6. Click "Undo" next to "We've updated the color scheme to match your logo"

That should do it. I couldn't get the first schema to stick.

Thanks again for ALL the hard work your team puts in. It makes my job and my departments look great.

Steve
