Only thing new is that the animation is no longer as funny looking. This is a height slider based on simmythesim first height slider. Remove the old one and place this in your mods folder unzipped I added the fix to one of my downloads (heightslidertoddlerfix), and will hopefully add it them all once I have more time.
A toddlerfix is made by vectorplexus for the old sliders by simmythesim.
