The issue is with the Microsoft Viewers. Remember that the whole existence of the VIEWERS is to occupy the whole screen and that's it. However, if you install PPT from Office, then you can get the PPT files into a small window in a size to your liking. But again, you have to go to the PPT application and request the PPT file to eb dipslayed in a small window and also without the scroll bars.
MagicInfo-I makes use of other applicatioon resources, it can't do everything by itself.
