Hitting Backspace When Trying to Delete Img Sends User Back

Hello,
It appears that when using CKEditor in IE (and possibly FF) and you select an image in the editor window and try to delete it using the "backspace" key, the browser thinks you want to go back instead.

I believe that this problem could be solved by a script like:

function stopKey(evt) {
var evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
if ((evt.keyCode == 8) && (node.type=="img")) {return false;}
}

But I'm not exactly sure where to put it in the new CKEditor folder (or if it would even work).

Any one else run into this problem and/or have a possible solution?

Thanks,
Dave
