OE and O2003 (and earlier versions) seem to know which panel in the program you have your mouse over when you roll the mouse wheel. You don't have to click into the panel to tell it. For example, if you have Outlook open and you hold your mouse pointer over the mail folders panel and *without* clicking into it you move the wheel, the folders scroll up and down. Then if you move over to the panel that shows what's in one fo the folders (inbox for example) and again *without* clicking into that panel, moving the wheel again scrolls the contents of that panel, not the one you were in before. There are other programs that do this as well. However, this is NOT the case with Windows Explorer which I use all day long. It's very annoying that you have to click into the panel on the right that shows the tree of folders in order for the wheel to scroll that area. It would seem that if MS can make O and OE behave properly then they could do the same with W.E. Seems logical but oh well. Maybe this is fixed in 7? It would just be nice if it were a consistent behavior in software that comes from the same company.
