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 also now noticing the Wife 1.0 is also spawning
Child-processes which are futher 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
the system initialization where it can monitor all other system
activity. Some applications such as PokerNite 10.3, BachelorParty 2.5,
and Pubnite 7.0 are no longer able to run on the system at all, causing
the system to lockup when lunched even though the apps worked fine
before.
Wife 1.0 provides no installation options. Thus, the installation of
undesired plug-ins such as Mother-In-Law 55.8 and Brother-In-Law Beta is
unavoidable. Also, system performance seems to deminish with each
passing day.

Some features my friend would like to see in the upcoming Wife 2.0:
   A "don't remind me again" button.
   Minimize button.
   Ability to delete the "headache" file
   An install feature that provides an option to uninstall 2.0 version
without loss of other system resources
   An option to run the network driver in "promiscuous mode" allowing
the system's Hardware Probe feature to be much more usefull/effective.
He also confessed that he wished he had decided to avoid all of the
headaches associated with Wife 1.0 by sticking with Girlfriend 3.0. Even
here, however, he found many problems. Apparently you cannot install
Girlfriend 4.0 on top of Girlfriend 3.0. You must uninstall Girlfriend
3.0 first, otherwise the two versions of Girlfriend will have conflicts
over shared use of the I/O port.
Other users have also said that this is a long-standing problem that I
should have been aware of. Guess that explains what happened to versions
1 and 2.
To make matters worse, the uninstall program for Girlfriend 3.0 doesn't
work well, leaving undesirable traces of the application in the system.
Another identified problem is that all versions of Girlfriend have
annoying little messages about the advantages of upgrading to Wife 1.0

VIRUS ALERT
All users should be aware that Wife 1.0 has an undocumented bug. If you
try to instal Mistress 1.1 before uninstalling Wife 1.0, Wife 1.0 will
delete MSMoney files before doing the uninstall itself. Once that
happens, Mistress 1.1 won't install and you will get and "insufficient
resources" error message. To avoid the aforementioned bug, try
installing Mistress 1.1 on a different system and "never" run any file
transfer applications (such as Laplink) between the two systems.

FYI: Don't even think about a shared directory!!!!!!!!
