Help getting Remote Assistance to work?

Hi,

I live in Hungary, my mother lives in England and my brother and I have just
got her onto the net with a very basic Dell PC; he has done the basic
setup...

I need to help her complete the setup and generally support her, but when
she has "issued" Remote Assistance requests I am not even receiving the
invitation.

At her end she is using Windows Mail - and successfully sends and receives
email. Remote Assistance triggered the setup of Windows Mail so it knows
that is her email client.

At my end, I'm using Outlook 2002 - and have successfully sent and received
email to/from her.

The firewall at my end has Remote Assistance allowed through.

No more informaiton about the config at her end (which is why I want RA!)
except that her system is probably Home Basic (mine is Home Premium).

Anybody got any ideas what's wrong or how to get it going?

TIA

Julian
