Hello I'm new to Returnil, having used Sandboxie for years. So, a few questions (I'm using Vista): 1. What's the memory footprint and CPU usage? How many running processes? 2. Should System Restore be turned off? I assume any restore points created will be lost on reboot. 3. Any special considerations with regard to UAC? 4. Are there conflicts with any other application whatsoever? BTW, now that Castlecops is gone and along with it the Returnil forum, this seems to be the only place to discuss it.
