Running XP Professional 5.1 with Service pack 3 installed on a Dell 8400. Installed PM 4.6.1 and nearly every time that I exit out of the program, it stays running in Task Manager. I have to go into Task Manager and manually kill the process. Not that big a deal, but cumbersome. I have seen other posts on this issue dating back to 2006 and release 4.3. Is anyone else having this issue?
