White space inbetween modules

Hi,

Have a problem with a site I'm doing, white space inbetween each module on the front page?
Also how I do I stop the menu popping down on scroll without just removing width/pos from the CSS?

Thanks in advance, site is here:

I'll pm details as it is offline but I don't want to rudely PM without reply

Please send me a PM with:
1. URL to your website
2. login and password of user with login privileges (please create one for me)
3. link to this thread

Ah I sent you PM but forgot the link to this thread, will do again.
