I just got another response from ESET Customer Care. Here's what they had to say about the Application popups, that ESET seems to think that I'm the only one getting them: Isolated incident? In otherwords, this is only happening on my machine...right? Come on. I just installed ESS 4.0 on a third system ( that makes 2 completely different machines than mine) running XP SP3 and they're getting the popups too.
