Ask and Answer dialogs are so far off you can only see about the bottom 1/8 of an inch of the window and are thus unusable.

Yes, it has been working for us. It works in LC9.0.2 with a new stack 
and a button with those 2 lines in a mouseUp handler.

I think this may only work under Desktop OSes as the Inclusions (in 
Standalone settings) show the standard Ask and Answer Dialogs available 
only for Linux, OSX, and WIndows.

Also, per prior discussion in this thread, code like:

set the loc of stack "Ask Dialog" to effectiveScreenLocOfScreen(the 
sceeen of this stack)
ask "What color?"

where

function effectiveScreenLocOfScreen pScreen
   -- pScreen is a monitor number (a line of the screenRects or the value of the screen of stack property
   --
   local tRect,tH,tV
   put line pScreen of the effective screenRects into tRect -- or use 'effective working screenRects' for accommodating pop up keyboards and such
   put ((item 3 of tRect - item 1 of tRect)/2) into tH
   put ((item 4 of tRect - item 2 of tRect)/2) into tV
   return (tH,tV)
end effectiveScreenLocOfScreen

should result in centering an Ask Dialog on the monitor that the stack that invokes it is on.
