Excel 2010 Chnage Auditing - Combine Worksheet_SelectionChange and Paste?

[JeffK627]

I have a requirement to add change auditing to an Excel 2010 workbook. If the user changes the value of a cell in columns A, B, C, or J, I need to capture the old value, the datetime of the change, the username, and the new value that they enter. I was able to do that - this code captures the old value from the selected cell (I have another sub that does the rest):

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Dim r As Long
    Dim OldValue As String
    Dim AuditRecord As Range
    Dim wsManifest As Worksheet
    Dim wsHistory As Worksheet
    
        Set wsManifest = ThisWorkbook.Worksheets("manifest template")
        Set wsHistory = ThisWorkbook.Worksheets("ChangeHistory")
        
        'Limit range for change auditing to columns A, B, C, and J
        If (Not Application.Intersect(Target, Range("Tracking")) Is Nothing) And (Target.Row >= 3) Then
            Application.Calculation = xlCalculationManual
            Application.ScreenUpdating = False
            
            ' This is our change history ...
            Set AuditRecord = wsHistory.Range("A:E")
            
            r = 0
            
            ' Now find the end of the Change History to start appending to ...
            r = FindLastRow(wsHistory.Range("A:A"))
            
            'Old value - Preserve formats
            OldValue = wsManifest.Cells(Target.Row, Target.Column).Value
            
            If OldValue = "" Then
                With AuditRecord.Cells(r, 3)
                    .Value = "New Entry"
                    .NumberFormat = "@"
                    .HorizontalAlignment = xlLeft
                End With
            Else
                wsManifest.Cells(Target.Row, Target.Column).Copy
                AuditRecord.Cells(r, 3).PasteSpecial xlPasteAll
                Application.CutCopyMode = False
            End If
        End If
End Sub

The problem is, users sometimes need to copy a value and paste it into another cell - for example, copy the value in cell A22 and paste it into cell A23. But the Worksheet_SelectionChange event clears the clipboard, so they can't paste. if I add an If..Then to check whether Application.CutCopyMode = False, then the SelectionChange event doesn't fire and the old value isn't recorded.

Is there any way to capture the existing value of the selected cell without losing the ability to copy/paste?
