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

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

1. Create and run a program with the following code:

  

        oTBar=CREATEOBJECT("mytoolbar")
        oTBar.Show
        READ EVENTS

        DEFINE CLASS mytoolbar AS toolbar

           Caption = "Toolbar1"
           Height = 109
           Left = 0
           Top = 0
           Width = 110
           Name = "mytoolbar"

           ADD OBJECT olecontrol1 AS olecontrol WITH ;
              OLECLASS="MSComCtl2.DTPicker.2",;
              Top = 5, ;
              Left = 5, ;
              Height = 100, ;
              Width = 100, ;
              Name = "Olecontrol1"

           ADD OBJECT cmdbtn1 AS COMMANDBUTTON
              procedure cmdbtn1.click
                 clear events
              endproc

        ENDDEFINE

2. When the ToolBar displays, click inside the Date Time Picker Control. You may
  want to either highlight a date value or click the DOWN ARROW key.

3. Using an ALT key combination like ALT+Z, ALT+C, or ALT+U and so on, causes
  the following exception error:

  Fatal Error: Exception code-C0000005 Called from ...........

  Clicking OK, the only option, shuts down Visual FoxPro.

NOTE: Any ALT key combination other than the Visual FoxPro System menu Hot Keys
(ALT+F, ALT+E, ALT+V, ALT+T, ALT+P, ALT+W, ALT+H) causes the exception error.
