Powerpoint return to slide ....

Hi, 

I have a slide that has some entrance and transparency animation, suppose some have been activated by clicking and then by action click, I leave that slide for a series of slides where at the end of them i return to this slide to continue, at this point the entranced objects are present but not the transparency effects (those are gone) ... how can I keep them in place as I return to the slide so can continue the presentation at the same state and condition I left the slide? 

Thanks for your help.
