WebPlus X7: Opaque Fade on Slider isn't working

Hi there,

I've just recently bought WebPlus x7 and tried out a few things like sliders which I will be using a lot. But, unlike on X6, the slider option 'Opaque Fade' does not do a fade, it just does it like a basic option instead. I've restarted the program and it still does the same thing. I've even opened up a website template I had created before on x6 that had a working opaque fade slider and it didn't fade either! Is this a x7 glitch or what?

Thanks!
