I'm not sure as to how many users of the aol browser there are. W3Schools hasn't had statistics on that browser since 2002. It seems that less than 0.7% of users use the browser (added up the main 7 and ended with 99.3%). I'm not sure how much effort you want to put into getting it to work in that browser. It isn't a browser that is supported or tested on for us.
Here are the browser statistics:
