I love and have been using Sandboxie for several months now. I was so impressed with it that I'd used it less than a day and I paid the $25. However, from viewing this forum, I understand many of you use more than one program per session. With Returnil and SafeSpace already free and DefenseWall free today I just can't decide what route to take, if indeed any, relative to another sandboxed environment. Also, there is MS SteadyState final release upcoming the first part of the year.
