Well, I was staying away from system mode only because PA strongly suggests so. Actually looking at "what is wrong with system mode?", all security issues are moot for me, as I own all the users on the system. But the point When in system mode, shared memory data transport is disabled for security reasons, which means: much higher memory usage and CPU load in system mode does sound bad. Could someone quantify this statement so that one might see if this is an actual issue (rather than a mere fact) on a modern desktop system? Ralph
