Hi Carman,
I think the poster above is on to something. My mom had AOL until recently, and I used to help her sort her stuff out when she had problems. I remember that AOL had their own program that was both browser and email client. Is that what you're looking for?
It would seem they still make that program for Mac, but I think I also heard you say it's not working that well. If you really want to get that type of interface back, then a complaint to AOL would be one place to start. Skimming through the article it seems they have a new version out, and it might not be bug free yet. So they need to hear from you as to what problems you're experiencing.
Until they get it "fixed", if you can't abide using the AOL software, then I'd recommend what others have: use any other internet browser to access their web page and the internet. You can also do web mail off of their home page (aol.com). OR, as suggested above, use an email client like "Mail" or "Thunderbird" to get your mail (from my quick scan of various articles, it would seem you can use just about any email client with AOL). So you'll end up with two programs running somewhat separately instead of one, but in my opinion it will work better than AOL's program once you get used to it.
Does that help, or is there something else you're getting at?
