Windows 7 Desktop Slideshow problems

Hi guys. Alright,I've been using static wallpaper for a while and last night , i try using slideshow function. Yes it works but the problem is there's no transition. No fade in or fade out. The wallpapers just change in a blink . Can someone provide me solution :)?
Thanks for helping
