BSOD when scroling messages using Outlook 2007 with Outpost 4. sandbox.sys is causing error. There are many people with this issue since the Fall of 2006. No response from Agnitum in their forums. The Uninstaller is flawed. After uninstalling and removing all registry entries, XP Pro Security Center still states that Outpost is on. The only fix is to install an old version 3.5, and then uninstall this version. I am sick and tired of these software companies putting out sloppy and unfinished programs. It is a disgrace. Never again will I buy from Agnitum!
