Clicking on the Summary button in the Analysis Options dialog box opens the Summary of Options window. By default all possible options are displayed with unused options grayed out. If you wish to display only used options, select the Hide Unused checkbox at the top of the dialog box. If you do not wish to have any options grayed out, clear the Gray Out Unused check box. A Yes or No appears before each option to indicate if the option is being used (this is useful if you are not graying out unused options). If you do not wish this text to appear in the dialog box, select the Hide Yes/No checkbox.
