I don't know about incompatibility--that sounds like a copout. I just think that the AOL software and an integrated browser are too much if you use both for any length of time. Some of the Facebook and apps features just work better with Firefox and/or Chrome. They are both faster and more secure than IE in any form (including on AOL).

I've been bold by a computer tech there is an incompatibility between Face Book and AOL. Hugs Pat Arden and Pat Houser Pahrump NV History Buff May God continue to bless America
