Match! provides a large variety of options for the setting of colors, line styles and fonts for all kinds of dialog elements, so that you can adapt Match! to your personal preferences. These settings are defined in the "Colors and line styles" dialog which you can open by pressing the corresponding button in the toolbar at the top of the main window.
The dialog consists of 5 parts (tabsheets):
If you mark the "Save as defaults" checkbox at the bottom of the dialog before you close it by clicking "OK", the current settings will be stored in the registry so that they are restored next time your start Match!. You can also save the current settings explicitly by selecting the corresponding command in the "Tools" menu. This is generally appropriate if you changed some options using toolbar buttons instead of the "Options" dialog.
If you are in doubt whether your default settings are still appropriate, you can restore the original (Crystal Impact) settings using the "Restore factory settings" command in the "Tools" menu.
