Exporting a group from Outlook Express

Hi,

Can anyone tell me how to export an outlook express address group? I have exported the address book as a CSV file but it doesn't included the group within the exported file.
I specifically need it to be a CSV so that I can import it into another mailing list program.
I've also tried selecting all the addresses in the group and hitting CTRL C, but it doesn't let me copy.

Thanks in advance for your help.

Michael
