Button Position/Coordinates On Worksheet. Discrepancy Between Versions

Add Multiple Buttons That Select Row Of Housing Cell. One of my Macro's places a button on a sheet using Top/Left;

Set sbut = Sheets("Listings").Shapes.AddFormControl(xlButtonControl, _
Range("J" & count).Left, Range("J" & count).Top, 50, 12)

When I try to find the row of the clicked button using the following code;

Range(ActiveSheet.Buttons(Application.Caller).TopLeftCell.Address).Activate

The code behaves differently in Excel 2002 and 2007. In 2002 it returns the row the button sits on, but 2007 returns the cell above the button. This could be because the workbook is an XLS running in Excel 2007 in compatibility mode? Is there a way to "nudge" the button down a little after it has been placed using .top/.left ? Or is the only way around this something like;

Range(ActiveSheet.Buttons(Application.Caller).TopLeftCell.Address).Activate
count = ActiveCell.Row
If Application.Version >= 12 Then
count = count + 1
End If

Is this a bug, or something that I am doing wrong ? The workbook needs to be a .xls to ensure that it works in older versions of Excel.
