George, I'm using 1.76.6715 on Windows 7 64 bit. Two things you should check. First under Settings make sure that Show Small Object Halos is turned on to see the halos. Secondly in order to see the Display Options dialogue box you need to first select a small object (either the object or the halo if you have halos turned on) with a left click. Then once selected right click on the object and the Display Options box should open. I you just right click on an object then ADE treats this the same as a right click anywhere on the graphics window.
