After upgrading to ZoneAlarm Extreme Security v9 and ForceField v1.5, I can no longer type foreign language characters in any browser. When switching to Japanese character input, the characters come out at random instead of the letters I’ve actually typed. The new version of ForceField has completely screwed up this functionality. If I Turn Off ForceField then the language support works again.
Before v9 of ZA Extreme Security language support worked without problems.
(Foreign language support is standard with XP. You can enable it by configuring the options under the “Regional and Language Options” in Control Panel.)
