This sounds much more like a browser issue than BB or Windows.
If you've found a browser that works you've found the best solution.

My wife uses one browser for email on one provider, and a different browser for another.
If it works, why fix it?

I'm guessing here but maybe your AOL browser is based on IE, which is much different than Chrome.

I do not work here, but the benefits are still awesome
