Now that the problem has been identified, someone can easily fix it with
a binary patch. I still use FullWrite 1.0 (and I use it quite a lot) and
it also has that problem. I'll probably try to patch it the next time I
need the set margins dialog.

The easiest fix would be to write an FKEY that moves the front window onto
the main screen. Running this FKEY would then make the invisible dialog
visible.

To patch FullWrite itself, one has to drop into the debugger at the
correct spot (easy to detect with TMON) make changes to the code
resource, call ChangedResource and WriteResource on the CODE resource
that was changed. This will make the application slightly larger,
because FullWrite compresses most CODE resources. Fortunately it
checks for the compression, so writing the uncompressed resource
doesn't make it malfunction.

I've done some FullWrite binary patching a few years ago. The FKEY
solution is by far the easiest and as such I recommend it.

Actually, I just noticed I had some time on my hands, so I wrote the
FKEY for you. It took me 15 minutes and it seems to work with everything
I tried (a few applications), so it's not really FullWrite-specific.
The Set Margins dialog works now beautifully.

I'm including the source code and a very short BinHex file with this
message. Use ResEdit to paste this resource into your copy of FullWrite
and hit cmd-shift-8 after the Set Margins button. Voila!

Think C source:
void	main()
{
	GrafPort	DummyPort;
	Rect		MainScreen;
	WindowPtr	FunkyFront;
	Point		Movement;
	
	OpenPort(&DummyPort);
	MainScreen = DummyPort.portBits.bounds;
	ClosePort(&DummyPort);
	
	FunkyFront = FrontWindow();
	
	Movement.h = (MainScreen.right-MainScreen.left
		      -FunkyFront->portRect.right+FunkyFront->portRect.left)/2;
	Movement.v = (MainScreen.bottom-MainScreen.top
		      -FunkyFront->portRect.bottom+FunkyFront->portRect.top)/2;
	MoveWindow(FunkyFront,Movement.h,Movement.v,0);
}

(This file must be converted with BinHex 4.0)
