Hide close icon on window

Hi,

In my scenario I have two actions in the action bar as follows:

$("#requestWindow").kendoWindow({
        draggable: false,
        resizable: false,
        modal: true,
        title: "My title",
        actions: ["Refresh", "Close"]
    });

What I want is to only hide one of the actions.

This will hide both actions:

$("#requestWindow").parent().find(".k-window-action").css("visibility", "hidden");

And this hides one option but you can still hover the "invisible" button (see attached image):

$("#requestWindow").parent().find(".k-i-refresh").css("visibility", "hidden");

Any ideas on how to prevent this "hovering" effect?

Cheers
