Some controls won't display, it has something to do with the script
ig_webpanel.js line number 124 :
this._expandEffectGenerator._contentArea.firstChild.style.overflow="hidden";

If I put this line in comment, the controls will display, if I remove the
comment, nothing is shown.



Putting it in comment has major consequences on other controls which will
result in an unrecoverable error in our webpages, so it's not a solution
we're happy with.



Any idea what's going wrong ?
