OK, I can live with the glitches, this is my major gripe:
To get PPN to run I have to get past this window:
And I have to uncheck the box that says "Protect my computer from viruses ...", otherwise, PPN starts, but it won't run the Update, and it won't run at all.
Why does this window even come up in the first place? I have a standard WinXP system and NO OTHER program I have ever run ever asks me to do this.
