InDesign CS5. Placed editable PDF file but now cannot select text or images. Both text and images can be selected from the original PDF file and copied and pasted into Word and edited. However, when placed in InDesign, niether text or images are selectable. When using the Text Cursor all you see is a variable W and H dimension. The original PDF does not have any security setting that prohibit copying.
Waht you have when you place a PDF is a link to the file, not editable content. You must edit the original PDF in Acrobat. You can certainly copy text from a PDF and paste it into ID for editablilty, but pasted images are not editable, only scalable, cropable, or positionable -- ID simply doesn't have any ability to edit pixels.
