Darryl,
Thank you for your answer. I looked at undecorating the frame but that does not give me what I'm looking for. I am attempting to emulate, in a very small way, the World of Warcraft GUI and functionality. The main panel/screen that holds the action bars and the game field for WoW does indeed have an undecorated frame. However, if you open the Spellbook, the Spellbook does have a frame of some kind and it is immovable. (I don't know why Blizzard wants it immovable but all of the "dialogs' you can bring up in WoW are immovable. I agree that usually I'd let the user move the windows wherever they wanted to.)
I am beginning to think that the Spellbook actually has an undecorated frame and that Blizzard has added some elements at the top to make what looks like a frame's titlebar and a close button. I may need to do that. Does that make sense to you? Any other ideas on making an immovable frame?
Actually, I'm trying a JWindow and I think that's working - I'll add a titlebar and close button and see what I get; still interested in any other ideas you might have.
