I own a Google Apps domain, and I've built a site in google sites. Within the site I've embedded some gadgets, added by url.

The problem occurs when I open the site in Chrome: the gadgets aren't displayed and there's a white space instead of them.
This doesn't happen when opening the site in Firefox.

Here's the difference. This is the page as displayed in Firefox

![page with gadgets dispalyed][1]

This is the page from Google Chrome, instead (without the gadgets)

![enter image description here][2]

How can I prevent this behavior? I'm aware that the gadgets loaded by an external url can be seen as non-secure items, but why chrome is blocking them at all?
