jQuery UI Dialog and CTRL + V

jQuery UI Dialog and CTRL + V

Hi,

I have created an jQuery UI Dialog with modal: true.
Everything works fine but in FF and Chrome i.e. CTRL+V doesn't work in the dialog.
The only texts which I could copy are texts from input fields or textareas but no "label" texts in a span oder div or something.

When I change it co modal: false, it works fine. But this is not what I need.

And in IE 8  it works all fine.

Could any one help me please.

Thanks
