Problem:
What do you do if you cannot do exact placement of objects on a graphical Dialog System screenset window?
Resolution:
If you add new objects to a graphical screenset window and they seem to have a snap-to-grid behavior where you cannot place them exactly, then select the Dialog System Edit menu, Alignment menu, and notice the values for X axis and Y axis under the Grid increments group.
You may need to change these values to 1 if you want exact placement of objects on a window.
