I have installed Outlook 2007 on my PC running Windows Vista Home Premium. I
have set it up as the default mail client in both Outlook and in the start
menu under default programs. BUT I am constantly getting this error message:

Either there is no default mail client or the current mail client cannot
fulfill the messaging request. Please run Microsoft Office Outlook and set it
as the default mail client.

I get this message on every send and receive AND Outlook will not save my
toolbar preferences, I just get the error.

Any suggestions would be appreciated.

thanks,
