Last year a friend of mine upgraded from GirlFriend 6.0 to Wife 1.0 and found that it's a memory hog leaving very little system resources available for other applications. He is now noticing that Wife 1.0 is also spawning Child Processes which are further consuming valuable resources. No mention of this particular phenomena was included in the product brochure or the documentation, though other users have informed him that this is to be expected due to the nature of the application.
Not only that, Wife 1.0 installs itself such that it is always launched at system initialization, where it can monitor all other system activity. He's finding that some applications such as PokerNight 10.3, BeerBash 2.5, and PubNight 7.0 are no longer able to run in the system at all, crashing the system when selected (even though they always worked fine before). During installation, Wife 1.0 provides no option as to the installation of undesired Plug-Ins such as MotherInLaw 55.8 and BrotherInLaw Beta release. Also, system performance seems to diminish with each passing day.
