Description Felipe Heidrich CLA 2011-01-17 16:33:20 EST 
In Firefox, if the edtior is hidden by setting display to "none", the caret will not draw once the editor is made visible again.

Paste this in the demo.html:

function test() {
    var parent = document.getElementById("divParent");
    parent.style.display = "none";
    setTimeout(function(){
        parent.style.display = "block";
//        editor._clientDiv.contentEditable = false;
//        editor._clientDiv.contentEditable = true;

    }, 1000);
}

In addition to that, I also see the Ctrl+C/V shortcuts stop working, and text selection behaves wrong when using the mouse.

Does Orion hide/show the editor ?

Simple test case that shows the problem without using the editor.
