HTML & images will not stay on same line in Internet Explorer

Hi

I'm a newbie to this so hope I can explain the "challenge" I am having.

I have built a proof of concept site with TMA as the theme using Firefox and Safari on a Mac - When I test on Windows (Vista) it works fine in Firefox but if I have used HTML in a node or a block (for a mix of images and text) IE7 pushes each content item onto a new line. If I revert to the Garland theme everything works as it should.

Have a look at this page for a (hopefully) clear example:

I am a newbie Drupal user and pretty amateur at CSS and theming. I have made a few overrides at the end of the tma.css file however if I replace that with the vanilla TMA theme and test it still does the same thing.

Appreciate any help - it is a great style and would love to use it.
