I docked my toolpalette and closed it. I then selected something from the drawing, did a right click and selected Properties from the right click menu. The Properties Palette opened. See if that works for you.
fyi: i am working with corridor object off the palette. found out what it is. when i click on something off of the tool palette, the properties box is suppossed to automatically open; rightfully so, to edit the objects. mine doesnt open when i choose something off the palette. is there an (weird) option/toggle somewhere that will auto. open the prop. box?
