A dialog box is either presented within an already opened window or it may appear as a new window. Usually, all other menus are disabled until the dialog box has been exited.
All input is checked after the dialog box has been exited through the [Ok] button. In some dialog boxes the exit buttons are labeled differently, e.g., [Load], [Store], or [Apply] etc. If an invalid entry is detected, the dialog box is reopened and the user is requested to correct the entry.
The button [Reset] restores all values to the settings prior to opening the dialog besides those confirmed through an exit button in an subordinary dialog box.
Exiting a dialog box through the [Cancel] button alse restores all values to the settings prior to opening the dialog besides those confirmed through an exit button in an subordinary dialog box.
Note that depending on the current window layout, certain dialog boxes may appear hidden behind other windows. This is especially true for requests-for-confirmation which are usually displayed within the main window.
