When I try to save something in PortableAbiWord, and I click on "My Documents" on the left of the open/save box, it brings me to the My Documents folder that you included with the AbiWord package. Then, after that, when I try to go to "Justin's Documents" in "Files Stored In This Computer" in My Computer, it defaults to this new directory that is included in the PortableAbiWord package. I have to System Restore to fix the problem. It does however, let me get to my real documents when I go to Start>My Documents. Maybe to fix this, one could rename the included folder to something Windows won't do anything special with, such as "Documents". Or, one could just eliminate that folder altogether and just have people save to their USB sticks.
