When there is a StartMenuShortcutsDlg after a ShortcutsDlg, show StartMenuShortcutsDlg only if "Start Menu Programs folder" has been selected in ShortcutsDlg.
This can be done very easily, just add the two dialogs and then right click on StartMenuShortcutsDlg and select "Show only if" than set the condition using the property attached to the corespondent checkbox from ShortcutsDlg.
Please note that dialogs can be conditioned only through our dialog editor which is available only in Enterprise and Architect projects. So the "Show only if" option cannot be used in Simple, Professional or Java projects.
