A blank space will print right over the graph or data table when the Always Show Printing Options Dialog Box is checked on the Printing Options menu on a Mac. To avoid the blank spot, go under File / Printing Options and uncheck the “Always show Printing Options” dialog box.

The blank area occurs because the area of the screen that had the dialog box does not have the chance to refresh and redraw before the screen is captured for printing. This bug only occurs in versions of Logger Pro before 3.0.
