The list of plant symbol categories across the top of the plant symbol selection dialog box is spaced strangely. As a result, you are unable to access the menu of symbol categories (pictured below).
This issue is usually the result of a corrupt font on your computer.
To correct the problem, follow our steps to fix a corrupt font.
Many of our dialog boxes use the Arial Narrow font. When you check for specific fonts that may have become corrupt, Arial Narrow is a good place to start. For example, the Planting dialog box, pictured above, looks for Arial Narrow (ArialN.ttf). If this font is missing, or if its filename includes extra characters, the dialog box will try to use the Simplex font. You should be able to fix the dialog box font by making sure the font is installed on your computer and editing the Registry listing for the corrupt font.
