why animation in slide show wont repeat until end slide?

I love your product and will never go back to Microsoft…
I have never donated money for any product of anyone and am guilty of not contributing…
You guys are doing a great job… ONE DAY I will donate… but not today…

This problem has been a problem with me since ms office 97 and in every version of any office…
I select the item to animate…
and it will do it as I selected the options… I am happy
when I select the option to continue an animation on an image or text for any selectable number of times it works…
I am happy

but when I select on ‘continue to animate until next click’ or ‘until end of slide’… IT WON’T DO IT!!!
NOT HAPPY…

all the apps have this same dilemma… for many years now I have never got anything to make this work…
Why will it not continue the animation until the next click?
why wont animation rewind???
I am sure it is my misunderstanding and all the help I looked at does not go in any kind of detail enough for me to understand… I am willing to be stupid… but so far… I do not know…
Help me please…

I know your busy and have lots to do and don’t get paid enough for morons like me…
But I will make a meal for the one who helps me out… pizza, pasta, fried chicken, burrito… you name it and I will make if for you… then you have to visit me to enjoy it… he he
