My problem: Windows ME, AOL 8.0 Zone Alarm 3.7 and Norton Anti-virus 2001. The problem appears to date from the installation of Zone Alarm.
I cannot download any web-based mail, but no problem with AOL email. Offered solutions so far have been to increase memory allocated to graphics (which speeded up those downloads which worked anyway), reconfigure Zone Alarm, uninstall ZA and re-install AOL (no effect).
AOL (my ISP) email works fine. For other email providers (Hotmail, Supanet and a client's in-house system) I can enter username and password info, but then I get a blank screen, usually a Window with 'Done' in the footer and the window itself a now familiar empty white.
Is it the free Zone Alarm? If so why don't you uninstall and use another free firewall such as Outpost ot Sygate Personal Firewall which will do the same job just as well. May be easier in the long run.
Yes, it is the free version of Zone Alarm, v3.7. Have already tried uninstalling it but that had no effect on the problem. Thanks for the alternative view though and I will try your suggested firewalls.
