SMS popup window not showing

In the browser wind on the computer with the conected cellphone are all my sms recipients shown. If I click on one of them a popup window occurs, but if there are more than 80 stored - this doesnt work. I can only see the little index-picture on the lower side of the window.FE and chrome on W7
