I can't find anything specific to why but I think there was a change in Excel from earlier versions to newer versions with regards to Activesheet.paste...??? maybe someone else can help with that..
I simply replaced Activesheet.paste with regards to cell selections and replaced it with activecell.pastespecial and all seems to be working fine.
NG,
note from modus_operandi: original file removed; please see
