PG trying to terminate itself?? "dcsuserprot.exe was blocked from terminating pgaccount.exe" I recently installed PG v 3.150 Full Version. Have XP SP2. When I "switch user" this alert starts and keeps going until I log out, thousands of times! It seems I can't have two users logged in at the same time. I don't know a lot about these machines. What is happening, and what do I do about it?
