Mail Notifier Problem

Hi
I am using DynAdvance mail notifier which works great on my XP computer.
When I click on read mail it will take me into my in box of Yahoo mail or AOL depending on which I selected.
I also have a Vista PC and although DynAdvance alerts me of mail arriving in either box when I click on read Yahoo mail it takes me inside the Yahoo box but when I ask it to read AOL mail it takes me into an empty Windows Mail box so I have to manually access my AOL box.
I have looked into the option of changing the email default to AOL but can't find a way to do this. AOL never appears as an option.
The other way I considerd was setting AOL to forward all mail to Yahoo but I can't sort this either.
Does anyone have any ideas ?
I would like an email notifier that also takes you inside your box when requested and which works with AOL.
