Note: Bit 0x40 ("Active window tracking Z order") is basically equivalent to "autoraise" in X. Clear the bit to enable autoraise (default), set the bit to disable autoraise.
In my Windows 7 installation, "ActiveWndTrkTimeout" is set to 500 (ms) by default, which is actually a pretty good default, maybe even a tiny bit fast. See http://technet.microsoft.com/en-us/library/cc957203.aspx
Edit: After living with it for about a week, I think it could use some improvement. It needs a "if the cursor sits still for X time, auto-raise. Otherwise don't." type of deal. It's annoying to be moving across windows to the other monitor and have them all auto-raise because they're wide and you stay inside them for .5 sec as you move the cursor across.
