Popup “disappears” when mouse pointer moves in IE9

Hi All,

I have a weird problem

When a icon is clicked say for modifying password a pop up needs to be displayed.

As soon as I move mouse pointer to this pop up it got disappears and when , again it get restored after clicking Restore Advance settings from internet options .Can it be cured with some tweak or is it to do something with GWT.

I doubt this has to do any thing with GWT because I am not seeing this problem in higher version of IE or any other browser like mozila,chrome etc.Regards
