	Small library for works with modal windows
	by YS, 13.12.2007

CSS:
	.bgFader{position: absolute; background: black; top: 0; left: 0; width: 100%; z-index: 99998; opacity: 0.5; // filter: alpha(opacity=50);}
	.modalWindow{position: absolute; border: 2px solid black; background: white; color: black; padding: 0px; overflow: auto; z-index: 99999;}

Use this class:
	var oMsgForm = new ModalWindow('msgForm');
	if(!oMsgForm.err){
		oMsgForm.setContent('ffffuel');
