I've extended more's Mask so I can apply an opacity tween effect to the mask... (and still have all the benefits of Mask, else I could use DWalsh's Overlay...)
Earlier I tried a simple way to extend Mask, just changing the showMask and hideMask methods: http://mootools.net/shell/A65x7/ But then I get the error: The method "parent" cannot be called. Q1. Why can't I call the this.parent() methods showMask and hideMask? Then I extended it in another way (needed to use it, so, went for the easy way out): http://mootools.net/shell/PMpZM/ In the original Mask show (and hide) methods it says: this.showMask.apply(this, arguments); Q2: When are these methods (show/hide) getting any arguments?
