Yes, and not for the first time either an AOL update that I neither asked for or wanted has been screwing things up.
I eventually fixed by clearing the browser cache
Start> All Progs> AOL> System Information (takes foever to appear)> Utilities tab> Clear browser cache.
I suggest you try this first and see if it makes any difference before " rebuild adapter" etc that also appear in the Utilities window.
Also, just switching everything off (including router), then on again is worth a try.
