I dunno if this was otherwise related here, but sandboxie 3.22 was released today. I just got it set-up and it's got some cool new features as compared to the last version. Here are some release notes from the site itself: Released on 13 January 2008. This page lists the changes to Sandboxie from version 3.21. This version improves the overall stability and usefulness of Sandboxie through various bug fixes and enhanced functionality: Improved support for sandboxed program installations, in particular for online installers such as Windows Live and the Google Pack. Improved support for Windows 2000. Improved support for sandboxing 16-bit DOS programs. Resolved conflicts with several third-party security applications. Sandboxie no longer recreates shortcut icons and associations every time it is started. Support for internationalization in Immediate Recovery.
