Clarification please. Are you saying that the Navigation window is not part of Simpleviewer? That's where I'm having the problem. I thought it was the Simpleviewer plugin not holding the options. It's hard to tell who's window is whos.
BTW, I came across your Tiltviewer today, now this is totally awesome! I'm going to try getting it to run in Rapidweaver. I won't be buggin' you here about that combination.
