<-Property Sheets
The values of Parameter on the current sheet are applied to the current dviout session.
If you have changed the parameters on other sheets, you will be asked to select from the followings: change on that sheet (Yes), skipping (No), or canceling previous changes (Cancel).
If cancel is selected, the process stops on the page being displayed.
The [Apply] button is disabled when no values of the parameters have been changed on any sheet.
