Thanks Joe, I will look out for that. I have mainly noticed it with Fade In/Fade Out. I must stress that the problem occurs when the click (to hide) is during the current animation.
For example, you have slides A,B,C,D….you want to get from A-D quickly. When you click next 3 times, the fade IN will occur for slide B and then immediately need to hide but it won’t, the fade IN will carry on until it is complete, resulting in multiple slides being shown. I hope that helps explain the issue.
