I ran this code from the Workbench command line in IDL 8.0 on Windows
XP-64. If the Workbench is maximized, I cannot even click on the plot
window in the taskbar to bring it forward and look at the plot. It
becomes usable after I type 'quit'. However, if I make the Workbench
smaller so I can see the Direct Graphics window behind it, the plots
work fine and do not go blank when I click inside the Workbench.
