Keith,
Try This approach. Put these bits of code in separate modules

fncWindowsTimer = CBool(WindowsTimer)
DoEvents
End Function
Public Function fncStopWindowsTimer()
KillTimer hWnd:=FindWindow("XLMAIN", Application.Caption), _

End Function
and change your activate event to just this
Private Sub UserForm_Activate()
Set timer = Me.Label1
StartClock
End Sub
There is also a StopClock function, so you can add a button to stop it.
