-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

In Visual FoxPro 5.0, clicking the Close button (the "x" in the upper-right
corner of the form) of a Top-Level form destroys undocked toolbars. However, a
docked toolbar is not destroyed. Pressing the Close button should not destroy
the undocked toolbar. This happens prior to the QueryUnload event of the form
and cannot be controlled by the developer.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug has been corrected in Microsoft Visual
FoxPro version 5.0a for Windows.

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

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

1. Place the following code in a .prg file and run it. A Top-Level form,
  Myform1, with a docked toolbar appears.

        **** Program Example****

         PUBLIC goForm
         goForm = CREATEOBJECT("myform")
         goForm.Show()

         DEFINE CLASS myform AS form
           BackColor = RGB(255,255,255)
           ShowWindow = 2
           oToolbar = .NULL.

           PROCEDURE Activate()
             IF ISNULL(THIS.oToolbar)
               THIS.oToolbar = CREATEOBJECT("mytoolbar")
               THIS.oToolbar.Show()
             ENDIF
           ENDPROC

           PROCEDURE QueryUnload()
             NODEFAULT
           ENDPROC
         ENDDEFINE

         DEFINE CLASS mytoolbar AS toolbar
           ShowWindow = 1
           ADD OBJECT mybutton AS commandbutton WITH ;
            Top = 5, ;
            Left = 5, ;
            Height = 22, ;
            Width = 24, ;
            Caption = ""

           PROCEDURE Init()
             THIS.Dock(0)
           ENDPROC
         ENDDEFINE

         ****End of Code Example****

2. While the toolbar is docked, attempt to close Myform1 by clicking the close
  button of the form. Since the QueryUnload contains the NODEFAULT command, the
  form does not close.

3. Now, undock the toolbar and attempt to close Myform1 again by clicking the
  close button of the form. The undocked toolbar disappears.
