If a Tool Palette is missing from your Naviate Tool Palettes, you can in many cases solve it yourself from inside the program.
Start by Right-clicking on the Tool Palette-heading (at the top of the Tool Palette or on the side of the Tool Palette) and select Customize Palette.
The available Palettes are displayed on the left side of the dialog and the Palette Groups are displayed on the right side. You an drag and drop the palettes from Left to Right. You can also right-click on a palette on the right side to Remove it from the Palette Group.
Once a palette is visible you can right-click on that palette (you need to right-click in an empty space on the tool palette to get this right-click menu) and select View Options to change the size of the icons and set the View Style of the Tool Palette.
