[Solved] Jumpy behaviour when dragging non-modal window

[Gunnar]

Hi.

I am experiencing jumpy behaviour when dragging the non-modal telerik window in Chrome and IE9. The telerik wondow is placed over an iframe delivered by an external vendor. The problem is that mouseover events are firing in the underlying iframe, causing timeconsuming context-switches in the browser.

When using the telerik window in modal mode the dragging works fine, as it then creates semitransparent a div overlay, preventing the mouseover events from the iframe behind.
 
So ideally my solution wolud be to show the semitransparent div overlay(used in modal-mode) when dragging is started, and hide it when dragging stops. Something like: (Jquery syntax)

$( ".TelerikDraggableWindow" ).bind( "dragstart", function(event, ui) {
    $('#t-overlay').show(); 
});
$( ".TelerikDraggableWindow" ).bind( "dragstop", function(event, ui) {
     $('#t-overlay').hide(); 
});

Is there any way I can connect to/ or override the dragstart/stop event?

Thanks in advance:-)
