Two of my colleagues already mentioned the ActivateGadget() function that
was added to Intuition in 1.2.  If you do any significant work with gadgets
you should buy a copy of the 1.3 Libraries and Devices volume of the
ROM Kernal Manual, and get the 1.3 Includes and Autodocs book or order
the disk-version from CATS.  There are a number of gadget functions
added in 1.2 that are not documented in the 1.1 RKMs.  The 1.1 volumes
are white with a colored stripe.  The 1.3 editions are blue.

As well, if you intend to activate the first gadget when your window opens,
you should know that you should wait for the ACTIVEWINDOW IntuiMessage
before activating your gadget.  This is because a lot of Intuition work
happens asynchronously to your task, so when you call

	OpenWindow(...);
	ActivateGadget(...);

the window may not yet be open or active when ActivateGadget() is called.

So add ACTIVEWINDOW to your NewWindow.IDCMPFlags and rock on.
