ie7 and floats

I have a situation where I have a floated div and then next I have a div with text which has it’s width defined . If I override the width all works in every browser but IE7. If I get rid of defining the width of the div that the text is in, IE7 works fine, but some on the rotating banner dynamically sets width. javaScript sets the width wrong and the page lays out wrong.
I’ve tried floating the div with text to the right, but that doesn’t work either, in all browsers. Is there a solution to this?

Thanks in advance.

did you consider ie box model different implementation?

What do you mean with ‘overriding’ the width?

Can you give us a link to a live site or post the code here? That would help us to find the issue.
