Using JQuery Tabs

Using JQuery Tabs

Hi everybody, I have bug on IE 7 (Windows Vista) when I display JQuery Tabs using Asp.Net WebUserControl.  I have something like this:
 
   Usercontrol contain all script to display JQuery tabs.
   after that, in my Default.aspx page, instanciate 20 times my user control to display 20 records on the same page with the same layout. Everything work fine on Firefox, Chrome, IE8  but not on IE7.
  On IE7, the first time my page load, my tabs are display fine, but if I select a tab (example tab 2) and Its contain need to resize its area, then the next user control changes its layout for raison that I don't know. If I mouseover it, everything become fine.
