Last year a friend of mine upgraded from Girlfriend 4.0 to Wife 1.0 and found that it's a memory hog, leaving few system resources 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 phenomenon was included in the product documentation, though other users have informed me that this is to be expected due to the nature of the application. Not only that, Wife 1.0 installs itself so that it is always launched at system initialization where it can monitor all other system activity. Wife 1.0 provides no installation options.
Beta is unavoidable.
Also system performance seems to diminish with each passing day. I myself wish I had decided to avoid all the headaches associated with Wife 1.0 by sticking with Girlfriend 3.0. Even here, however, I have found many problems. Apparently you cannot install Girlfriend 4.0 on top of Girlfriend 3.0. Other users have told me that this is a long-standing problem that I should have been aware of.
