I have 2 questions on the use of process guard 1). I recently added new programs after a fresh Windows XP Home Edition XP SP2 Install and I was interested in resetting the security TAB list of applications back to default like PG v3 just got installed. Is it safe to remove all applications, then reboot with PG v3 in learning mode to restore those settings? 2). When I choose to permitt a program always, then choose block new and changed programs after updates I always see Error "the handle is invalid". After I uncheck that the program runs fine. It seems like I cannot lock PG v3 because anytime I want to use Internet Explorer I have to unlock it, to open the program. I gave IE6 access always.
