My sleep settings are always on 20, and it makes no difference if I change them.
Edgar, it kind of threw me as well when I figured out what MA3 was causing to happen, or not happen as the case may be.
I have no idea on this one. But my office setup is XP SP3 and its office 2k that I use here.
I've tested out the MA3 in windowed mode. Launch Excel & Word with no problem at all (with sleep setting range from -1 to 30).
My setup is a Acer laptop running Celeron 1.5GHz with 2Gig of ram. WinXP Pro SP3 and Office 2K3.
