Now that I've been using ZoneAlarm long enough for it to turn on its more restrictive mode, it seems to have trouble remembering stuff.

Whenever I click on a hyperlink in an email message, I get a warning:

EUDORA is trying to communicate with C:\Program Files\Mozilla\Firefox\firefox.exe by using DDE

I check off the box that says "Apply this setting to all suspicious behaviors exhibited by this application" and then click "Allow".

But this same warning continues to appear. To be honest, I can't say for sure if it reappears in the same Windows session or only after a reboot, but whichever --- ZoneAlarm seems to forget my instructions and repeatedly presents me with this warning.

How can I fix this behavior?

Operating System:Windows XP Pro
Software Version:7.0
