I'm having a problem with this page:

In Safari and Firefox (OS X) the page shows up fine, i.e. picture to the left, and to the right of it some text. Windows IE is another story however: once the text to the right becomes taller than the image, the content below lines up with the picture. I checked and the page does validate as xhtml 1.0 Transitional.

What am I doing wrong?
Thanks for any replies...
