Topic: modalWindow Plugin and select fields in IE

Hi,
I'm using xajax with modalWindow Plugin, to show popup messages/forms. Everthing works fine under FF, but on IE7 once I display the modal window, html select fields disapper from original page, once I close the modal they are not visible either. I have to refresh (via xajax) the divs to let the appear again.

Do you have any suggestion about this issue?

Many thanks
