You get to chose one of three methods for Place-n-Time to redraw the window when you move new portions of the surface into it: Pre-load redraw buffer, Show drawing progress, or Both of the above.

To set this option, choose Redrawing from the Options submenu of the View menu.

REDRAW BUFFER USAGE

The redraw buffer stores areas of the map image which you have moved out of the window.  These areas remain available so that they may later be moved back into the window.  They will remain available until one of two things happen: one, you move the map far enough that they are pushed beyond the edge of the buffer; or, two, you do an operation that totally makes the old image obsolete, such as zooming or loading a map from another series.

Your choice will affect how this buffer is used, and what you will see while the map is being drawn.  Your choices are:

    Pre-load redraw buffer.

Generally it is nice to have the buffer pre-loaded while the map is being drawn.  This choice ensures that any areas of the loaded maps which lie just beyond the edges of the window will always be available when you move the map.  Because the actual drawing will be done in the buffer before being copied to the window, you will not see the drawing in progress.
    Show drawing progress.
You may, at times, prefer to see the drawing in progress.  This choice will allow you to do that.  When zooming, or otherwise redrawing the map, this allows you to see each item as soon as it is drawn, rather than waiting until the drawing is complete.  (It may also be more entertaining than staring at the wait cursor.)  However, because the actual drawing will be done in the window before being copied to the redraw buffer, surrounding areas of the buffer will not be pre-loaded.  The only other areas available in the redraw buffer will be those which you have previously moved beyond the edge of the window.
    Both of the above.
This choice allows you to both pre-load the redraw buffer and watch the drawing in progress -- sort of.  With this choice the drawing is done in the buffer and the window is updated as each theme is completed for each map.  So you will not see each item on the map quite as soon as it is drawn, but soon after.  And because the window is updated once per theme for every map, the drawing will take a bit longer than usual.
