MORE INFORMATION
================

Steps to Reproduce Behavior
---------------------------

1. Make sure that you have Microsoft Exchange installed on the test computer and
  have created a valid Exchange Profile.

2. Create a program file and type the following code:

        oleMAPISession = CREATEOBJECT( "MSMAPI.MAPISession" )
        oleMAPIMessage = CREATEOBJECT( "MSMAPI.MAPIMessages" )
        WITH oleMAPISession
           .Signon()
              IF ( .SessionID > 0 )
                 oleMAPIMessage.SessionID = .SessionID
                 ACTIVATE WINDOW watch
                 oleMAPIMessage.FETCH()
                 SUSPEND
              ENDIF
         ENDWITH

3. Save and run the program.

4. When the Debug window opens (this may take a minute depending the speed of
  the computer), enter "oleMapiMesssage" (without the quotation marks) in the
  Watch window.

5. Expand the MAPI control (oleMapiMessage) and scroll down or up in the Watch
  window.

At this point, you will get an Application error and Visual FoxPro shuts down.
