If you're editing a large form in the 4D v6.5 Form Editor and scrolling in the Form Editor window isn't as fast as you would like, turn off the display of the grid (the pegboard-like pattern of dots in the background). From the "Form" menu, choose "Display" to open a hierarchical pop-up menu of display options. Uncheck the "Grid" option.

NOTE: The reduced scrolling speed caused by the grid is negligible on newer computers.
