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

WARNING: Close all running applications and save your data before following this
procedure.

1. Create a PRG.

2. Cut and paste the following code into the PRG:

  PUBLIC oform1

  oform1=NEWOBJECT("form1")
  oform1.Show
  RETURN

  DEFINE CLASS form1 AS form

     Top = 0
     Left = 0
     Height = 123
     Width = 138
     DoCreate = .T.
     Caption = "Form1"
     Name = "Form1"

     ADD OBJECT combo1 AS combobox WITH ;
        RowSourceType = 1, ;
        RowSource = "one,\two,three,four", ;
        Height = 24, ;
        Left = 0, ;
        Top = 12, ;
        Width = 100, ;
        Name = "Combo1"

  ENDDEFINE
   

3. Save and run the PRG.

4. Click the combobox drop-down list, using the DOWN ARROW key to arrow down the
  list.

5. After highlighting the third item in the combobox drop-down list, use the UP
  ARROW key to arrow up past the disabled item. Note that once the highlighted
  bar moves past the disabled item, Visual FoxPro hangs.
