Here's another question from a Windows beginner:

I'm using SetMapMode(hDC, MM_ANISOTROPIC) along with SetWindowExt() and
SetViewPortExt() to transform window coordinates into constant units
(I want 1000, 1000 to always be the bottom right corner).  This works
fine if I do a SetMapMode() etc. every time I redraw a window.  However,
if I only do it when the window is created (WM_CREATE message) it seems
that the window extent information disappears after I do something.  I've
been narrowing it down, but I haven't quite found it: I have no other
calls to these functions; the only other thing I can think of is GetDC() 
and ReleaseDC() doing something to this info.

Does anyone have any ideas?  If anybody is willing to look at the code,
I can mail it to you (it's less than 500 lines).

Thanks in advance!
