Monte - thanks for your interest, but I have had no luck so far. I don't see why the 'X=1...' formulation should work better than 'repeat for each...', but if it does, I guess it does. I chose 'repeat for each' because the Transcript dictionary warns that this is a slower method, and I had no real reason to need the index 'i'. Your solution implies that the controls on the card have unique consecutive numbers starting from 1, which I didn't realise was the case, and seems to be contradicted by the Transcript Dictionary which says "The expression control 2 refers to the control whose layer is 2" which implies that the numbers are not unique, since not every object is on a different layer. Also, I tried an experimental button with this script:

on mouseUp
repeat with X=1 to the number of controls of this cd
put (the name of control i of this cd) into line i of fld "MyList"
end repeat
end mouseUp

But this produced a runtime error. I suspect that "control i" in this context does not translate to stuff like "graphic i" or "image i" or "field i" according to circumstances, a usage I have so far found I have to organise myself. I tried a number of variations, but no luck so far.

As to the GM, I've read many messages suggesting there are bugs in the 1.1.1 Geometry Manager; and also some of the things I want to do don't relate directly to geometry (for example certain properties will have to be reset from arrays of values that relate to screen size in complex ways; some clusters of objects stay together but move to new bits of the screen; some background colours may change, etc.), and I therefore need a scanning structure outside the GM to change this other stuff, so might as well do the whole job there (I thought). But I will look at the GM again.

Erik, thanks but I don't see how this helps me at run time (in fact startUp time) within my app, but maybe I misunderstood your point.

Back to the cyber-drawing board. But I still do believe that Revo itself knows how to do this.
