Last time I installed PG 3.100 I got a warning (from WinXP Pro SP2) that PG is "unsigned" and I should be careful about installing "unsigned" software. Being the trusting (gullible?) sort when it comes from DCS, I installed anyway and all appears to be well. However, it would be more comforting for new customers/etc. if they didn't get this ominous warning from MS when trying to install a core security software kit. What does it take to "sign" the software and are there any plans to do so?
