MORE INFORMATION

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.
