Steps to Reproduce Behavior

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.
