The easiest thing to try is to make sure your windows are longword aligned
(i.e. 0, 32 ,64 etc...) horizontally. When you start your project make 
sure that the windows left edge is at a good location. If you drag
a hypercard window you notice that the window is gridded to word alignment.
So if your user drags one of you windows around you can check its location
and reposition it if nessesary. I know its against the HI rules to move
things around after the user moves it but the speed penalty is tremendous
if the window is not aligned. (even more so for color windows).
