Hello, Does anyone know of a program similar to Sandboxie? This is for a friend who has used Sandboxie on his laptop but since he recently installed a few programs required for school, cannot currently use it. I am not sure why, but he stated the instructor at this computer class stated that it cannot be used with the programs. Other than that he never had any trouble with Sandboxie and he would like something similar. He would like it to be free, but he is willing to pay. This is for a Win XP Pro system with SP3. Thank you.
