CSS-problem i FF2

Jag har upptäckt ett rätt drygt problem på en sida jag gjort.
Det visar sig med Firefox 2. FF3 och IE är det inga problem.

Sidan kapas (se sista bilden i länken) men trycker man uppdatera kommer hela sidan fram.

Det jag har använt till att styra height:en är

<div id="rightframe">

#rightframe {  	float: right; width: 225px; height: 420px; vertical-align: top; text-align: left; padding-top: 15px;

Den vänstra (som kapas)

#leftframe { float: left; width: 665px; height: 100%; padding-top: 5px; margin-left: 3px; vertical-align: top; }

Någon som har några idéer?

html { font: Arial 11px; margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px; height: 100%; min-height: 100%;} 
body { font: Arial 11px; margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px; height: 100%; min-height: 100%; overflow-y: scroll;}
