AppleScrtipt Msft Power Point Height

I was wondering if there was a way of controlling the height of a power point slide show? I saw in the dictionary there is a slide show window base object and a height property. But, I was unable to get anything to work with this. I am needing to start up a slide show, then set the height so it is not completely full screen (the bottom of the screen will always be showing a certain amount).

Any help would be greatly appreciated!
