a year later... I finally found an occasion to use FileParentView. Turned out that it was the older version; it was stable but will not Save. So I replaced it with the new version from July 2010. It will save but will not minimize; the minimize button will light up, but not do anything. I have to right-click the icon on the task-bar and use AnVir Task Manager > Minimize.
Is this only happening to me, or does someone else have the same problem?

Edited:
I forgot to say that merely clicking the icon in the task bar will do the trick,
-but the minimize button does not work here.
