Mass Effect does not come with any support for borderless window mode.  The only way to do so is to use a third party utility such as ShiftWindow.

There are also ways to do it with autohotkey

Is it possible to set borderless window mode?
I have a friend with an iBook G4 who is looking for a cheap backup option for her Mac running OS 10.4.  Money is tight, so getting 10.5 is not really an option (in addition to buy a backup drive etc, yes money is really that tight).

What suggestions can you offer for backups that's better than trying to remember to burn a CD once a month?
