banners not showing

Hi, I've been playing around with banners…but just can't get them to work in Chrome.

I have a demo site on as well as using a downloaded trial.

From what I see in the Design > Blocks is a banner “Build your own PC” that seems to be set up and configured correctly.

The code is physically there in the generated HTML:



But it simply isn't showing.

I presume others are having trouble too?

PS: I don't use FF nor do I use IE. It does however work in IE
