OK, mr mod, lets try again.

Hi, I'm a newbie so excuse me if you are nice or flame me if you are not, but I need to use an excel book (written in 2003v ) on my vista machine running office 2007. I know little about the settings etc but having amended the macro's it has been working for months.

Now it comes up with the "reference is not valid" error message and all I can do is wait for autosave and then crash out of it via task manager. This does not happen straight away but seems to be when I click on a free format notes section.

I saw mention of this message elsewhere on this forum but there was talk of vsb etc that means little to me.

If anyone can help I would appreciate it.
