I have a ViewPort object, which has a child Panel on its body. In my Panel's body I have a fitlayout element and also it has a tabpanel child control. These controls are placed in my masterpage. I add new tabs with a client-side javascript. But I have a problem with my tabs. I add a new tab to my tabpanel and new page has a link which referred to open a modal page with window.showModalDialog javascript. When I click to my link new modaldialog opens and after I returned from the modaldialog my tabs are sliding up thus I can only see the half of them. Am I missing some property?


Thanks for your support.
