Widget drag and drop error in Internet Explorer 9

Hi,

Just now I have seen that in Internet Explorer 9, when I activated Easy Mode, I can´t drag and drop the widgets to the side bar.
Clicking "Exit Easy Mode", all goes normally.

In Firefox and Opera all is correct.
But in Chrome and Safari, at the drag an drop a widget, all text is highlighted.

It´s Wordpress 3.3.1, and Easy Blogging 3.15.
