We need more information. The onmouseover event for a frame is generally too inclusive or broad to use for a resizing event for the entire frameset, but not knowing your setup, it could be an exception:

Please post a link to the page on your site that contains the problematic code so we can check it out.

And please give us more details about your objectives.
