Some issues may arise or correct themselves when you switch between previewing modes. Keep the following in mind:
Placeholders replace the preview content when the Preview Record option is not selected. If you delete an image as well as the frame containing the image, or delete a whole text string, when you deselect the Preview Record option, the placeholders will not appear as they have also been removed.
Changes in the Content Placement Options dialog box are not reflected until you click OK. Also, if the Preview Record option is selected, the data will not reflect the updated placement settings until you deselect and select the option again.
If you try to save the document in preview mode, you will receive a message prompting you to turn off preview mode before saving your document.
