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

- Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a, 6.0 
- Microsoft Visual FoxPro for Macintosh, version 3.0b 
-------------------------------------------------------------------------------

SYMPTOMS
========

You have created a form that contains a command button. The command button's
Default property is set to .F. In the form Init method, you call the SetFocus()
method of the command button. When the form displays, the Default property of
the command button is set to .T. and the command button becomes the default
button.

RESOLUTION
==========

Set the Default property of the Commandbutton to .F. after calling the
SetFocus() in the Init method.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

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

1. Run the following code from a program (.prg) file:

  PUBLIC oform1
        oform1=CREATEOBJECT("form1")
        oform1.SHOW
        RETURN

        DEFINE CLASS form1 AS FORM
           AUTOCENTER = .T.
           HEIGHT = 408
           WIDTH = 389
           CAPTION = "Form1"
           NAME = "Form1"

           ADD OBJECT text1 AS TEXTBOX WITH ;
              HEIGHT = 23, ;
              LEFT = 108, ;
              TOP = 48, ;
              WIDTH = 100, ;
              NAME = "Text1"

           ADD OBJECT command1 AS COMMANDBUTTON WITH ;
              TOP = 216, ;
              LEFT = 120, ;
              HEIGHT = 27, ;
              WIDTH = 84, ;
              CAPTION = "Command1", ;
              NAME = "Command1" , ;
              TABINDEX = 1, ;
              DEFAULT = .F.

           ADD OBJECT text2 AS TEXTBOX WITH ;
              HEIGHT = 23, ;
              LEFT = 108, ;
              TOP = 84, ;
              WIDTH = 100, ;
              NAME = "Text2"

           PROCEDURE INIT
              * SetFocus() here causes the behavior.
              ThisForm.Command1.SetFocus()
              * Uncomment the following line for Work-around.
              * Thisform.Command1.Default = .F.
           ENDPROC

           PROCEDURE Command1.CLICK
              WAIT WINDOW PROGRAM() TIMEOUT 1
           ENDPROC

        ENDDEFINE

2. Tab once to move to the first text box.

3. Press ENTER.

RESULTS: The WAIT WINDOW displays, indicating that the command button's Click
event fired.

Workaround
----------

To demonstrate the workaround, uncomment the line of code that sets the Default
property of the Commandbutton to .F.

NOTE: In Visual FoxPro for the Macintosh, KEYCOMP must be set to WINDOWS for the
behavior described in this article to occur.
