I installed Sandboxie and within 10 minutes of using it and visiting some legal adult websites, I began getting a "com surrogate has stopped working" error message whenever I tried opening a folder which contains video files and graphic files. This error continued even after cleaning out the Sandboxie and shutting down Windows and rebooting, I know it's related to Sandboxie because I have never visited those websites before and never used Sandboxie before. So I had to completely restore an older image windows to get rid off the error message. I will never use Sandboxie again, that's for sure. Something definitely "jumped out" of Sandboxie and tampered with my codecs and goodness knows what else. So is there an FREE alternative to sandboxie that actually works? BTW, I am running Windows Vista.
