MORE INFORMATION

Steps to Reproduce Behavior

1. Create a form in Visual FoxPro and add a list box to it.
2. Select New Property from the Form menu and in the New Property dialog box, type Listarray(100) into the Name text box.
3. Add the following code to the Init of the List box:

         FOR I = 1 TO 100
               Thisform.Listarray[i] = "Array"+ALLTRIM(STR(i))
         ENDFOR

4. Add the following code to the InteractiveChange event of the List box.

         xcount = 0
         FOR x = 1 TO This.ListCount
               IF This.Selected(x) = .T.
                    Xcount = xcount + 1
               ENDIF
         ENDFOR

5. Set the list box properties RowSource to 5 - Array and the RowSourceType property to Thisform.Listarray. Set the MultiSelect property to .T. - True.
6. Run the form and click on the first item in the list box. Hold the Shift key down and press the DownArrow key until all of the items are highlighted in the list box.
7. Release the Shift key and scroll back to the top of the list box with the mouse or press the PageUp key.
8. Press the Ctrl key and click on three or four of the items in the list box to clear them. Note that as more of the list box items become cleared, the more distorted the list box becomes.
