W10 X6 shortcut problem

[knowbodynow]

I have the following code run when I press shift and the fkey:

Sub DupDown()    'Shift+F

Set sr = ActiveSelectionRange

If sr.Count = 0 Then
        MsgBox "Nothing selected"
        Exit Sub
    End If

Set sn = sr.Duplicate(0, -sr.SizeHeight)
sn.CreateSelection

End Sub

This worked for as long as I can remember on W7 but now on W10 every third time I use the shortcut some other code runs and sends my duplicate to the centre of the page. This doesn't happen if I run the code from the macro manager.

Has anyone else experienced similar problems running Corel X6 on W10? It seems the keyboard shortcuts are getting scrambled. Anyone have any ideas how to cure this annoying issue? Thanks.

I have not seen this with Windows 10. I know, that isn't much help, sorry.
