Thanks for explaining this so patiently.

I understand the problem now but I can't reproduce it here so I need to ask you to help me pinpoint the cause.

If you don't mind, I'd like to ask you to please download the new build (34) of the program that I just put on the website. This new build will (hopefully) display a different error message with more info when you run that macro.

Also, a question. Which versions of Windows are running on the two machines?
