The display of the filled continents can be toggled on and off with the pull down menu. To change the display attributes of the filled continents the user needs to go to the layer manager.

Upon double clicking the filled continents icon the following panel will appear.

If the No Fill button is selected then this will effectively turn off the color fill..
If Line Fill is set then the continents will be filled with a line of the style choosen, at the angle and color of the middle section.
The Solid Fill selection will fill the continents in with whatever fill color is currently shown in the color well.

The current color is shown in the color well. Clicking in the well will bring up the color selection patch.

To change the color of the filled continents lines just choose the desired color in the patch and drag it into the well. Please note that no color patch will follow the cursor, only when you release the mouse in the well will the color appear.

As an alternative to removing the filled continents is to select the hide radio button. If a layer is hidden it will remain in the layer manager but will not be plotted.
