SYMPTOMS
========

Pressing the ENTER key while on a check box that returns one (1) from its Valid
event, causes Visual FoxPro to skip the next object in the tab order. Pressing
the Spacebar while on the same check box moves the cursor to the proper object
in the tab order.

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. Create a program that contains the following code and run the program:

        o=CREATEOBJECT('Ztest')
        o.SHOW()

        DEFINE CLASS Ztest AS FORM
           WINDOWTYPE=1
           ADD OBJECT chk1 AS CHECKBOX WITH TOP=5,LEFT=5,CAPTION='PPP'
   
           FUNCTION chk1.VALID()
              RETURN 1
           ENDFUNC
        ADD OBJECT txt1 AS TEXTBOX WITH ;
           TOP=35,LEFT=5,WIDTH=50,cVar='thisform.t1'
        ADD OBJECT txt2 AS TEXTBOX WITH ;
           TOP=65,LEFT=5,WIDTH=50,cVar='thisform.t1'
        ENDDEFINE

2. When the form appears, press the Spacebar and note that the focus moves to
  the first text box. Press the TAB key twice to move back to the check box.

3. Once you are back on the check box, press the ENTER key and note that the
  focus goes directly to the second text box. The first text box never gets
  focus.
