Might be a god idea to give AOL a phone call on this one [It's free] Because (1) Broadband should not time out, It's always on.
(2) Even if you where on dial-up it should not time out because your downloading and therefore the account is active. With AOL dial-up you can stay on-line 24/7 as long as your connection is active. The time-out should only come on if you leave your PC idle. j.
