Hi,

I am writing a macro program which copies the contents whole sheet1 of
workbook1 and paste it to sheet1 to workbook2. After that, the program
closes
workbook1. But I always got a prompt and saying that I have a large amount
of
information in Clipboard and it askes if I want to be able to paste into
another program later. Actually I don't want this prompt and closes
workbook1
directly. Anyone knows how to bypass this programatically?
Thanks!

Ivan
