Registration points

This is driving me crazy because I don’t know what’s wrong.

No matter where I put the registration point on a thingy (for example, say a graphic) in symbol editing mode the coordinates in properties always reference the graphic to the top left.

I’ve tried moving everything, that little orb that’s ‘supposed’ to be the registration point, the crosshair or whatever, but it still keeps referencing the graphic to the top left! I would very much like to be able to change where the registration point goes on a graphic, and not have the top left every time.

Oh, and I can’t seem to find the rules for these forums. Anyone know where they are?
