I am using the latest update for Zone Alarm Extreme Security:
Version 9.1.507.000, Vector version same, driver version 9.1.503.000, browser security 18.104.22.168
I am using XP with Internet Explorer 8.
I constantly receive the "instability" error window when I try to open IE8. I have to shut down Zone Alarm Security to open the browser.
Also, links in emails and on web pages do not open, and I cannot open a new tab in IE8 without closing Zone Alarm Security first.
I believe the links that do not open want to open a new page or tab. Links that simply change to a new page seem OK.
