I have recently bought a Macbook pro (OSX 10.6) and installed MS Office. Unlike Windows, Mac users can scroll up/down or left/right of an application even though the app is not in used, ie. I open powerpoint and chrome side by side, and powerpoint is the one being used, from time to time I need to google something, what I need to do is to move my cursor on chrome to scroll up/down. I have tried several applications about this function, they all work well, except MS Word. I wondered if anyone have had this problem. Thank you!
