Thank you for your comments.

Well, a lot of it might be due to the fact that the code is erroneous. Since you did not
do a mouse capture, you will have WM_SETCURSOR messages sent every time you move the
mouse, which will naturally cause the mouse to revert to its appropriate class cursor,
which for your case appears to be an arrow. The Sleep() call simply blocks the ability to
process that message, and is itself an erroneous addition to th code.

Use CWaitCursor.

In 1994 I used the code from Kruglinski to change the cursor to an hour
glass (see below). This does not seem to work in Visual C++ 2003.NET using
MFC. The cursor changes back to what it was, immediately, unless you put a
delay in it! Not very good! Any suggestions from the Visual C++ Team?
