Snec, I have to say I don`t understand what you have claimed. I wouldn`t have thought my method of connection would make any difference if the AOL software is not compatible with Vista. I don`t really know enough about it I suppose.
The thing is, you see, that connection via a router means that you would not even have to install the AOL software on your machine, as you do have to if using a modem. You would merely be using AOL's connection and there would be no software for Vista to "disapprove" of.
