Display a block in the colorbox

Hello all,

First thank you for this excellent module!

My question now:

I've created a page called "newsletter" and then created a colorbox node link in my menu to open that page in a colorbox. So far, everything is working.

However, my newsletter form is a block displayed only on that specific page (MailChimp module), If I access directly to the page, I can see it, but when the page is opened in the colorbox, the block is not displayed anymore.

I tried to change the block's url settings, it didn't work. Any idea how to achieve this?

Thank you very much!
