If you use File > Export to create PDFs from InDesign or InCopy, you may find it helpful to have the resulting PDF automatically displayed in Acrobat after it's created. Or, like Deb, perhaps this behavior annoys you and you'd prefer to turn it off. This pesky setting often leads to confusion and frustration, because it behaves unlike any other setting in InDesign.
The View PDF After Exporting option in the Export Adobe PDF dialog box is the key to making this work the way you want it to. If this option is checked, then PDFs created from InDesign will automatically be displayed on the screen after they're created. If this option isn't checked, the PDFs won't be displayed.
The tricky thing about this setting is that it is NOT memorized with any PDF Presets that you create. To enable or disable this setting, you need to open an InDesign file, and then choose File > Export and select Adobe PDF for the format (or choose File > Adobe PDF Presets and select a preset). Then, in the Export Adobe PDF dialog box, select or deselect "View PDF After Exporting", and click the Export button.
You must create at least one PDF with the setting selected the way you want, and then it will "stick" that way until you change it again.
