Steps to Reproduce Behavior

Place the following code in a program file.

        **************************************************************
        *!* Start Error Example (Form)
        **************************************************************
        ox=CREATEOBJECT('oForm')
        ox.VISIBLE=.T.
        READ EVENTS
        *****************************************
        DEFINE CLASS oForm AS FORM
           NAME='MyFormFoo'
           ADD OBJECT oCommand AS COMMANDBUTTON
           ADD OBJECT oClose AS COMMANDBUTTON

           PROCEDURE INIT
              THIS.oCommand.LEFT=100
              THIS.oCommand.TOP=100
              THIS.oClose.LEFT=100
              THIS.oClose.TOP=200
           ENDPROC

           PROCEDURE oCommand.CLICK
              WAIT WINDOW   THISFORM.ACTIVEFORM.NAME
           ENDPROC

           PROCEDURE oClose.CLICK
              CLEAR EVENTS
              RELEASE THISFORM
           ENDPROC

        ENDDEFINE
        **************************************************************

Run the program and click the oCommand button. This returns the following error:
