"rightmost icon with the wrench"? What are you referring to? I don't see any preferences section. I see a set of icons at the bottom of the screen when running MediaBox and the rightmost one is the icon of the time/date. How would I get to the preferences section? There is a curved arrow on the lower left, which seems to change the bottom display depending on which icon has been selected. I cannot make the program come up with less than the entire display. There is no normal control panel (unlike any other IT application I've run). I have no images or media files in MyDocuments.
