Here's the explanation. When I transferred the document to Pages, I did a copy and paste of the text boxes and graphics. What I didn't understand was that, after they were in Pages, they would no longer need to be edited.
I have been printing the brochure from the Pages document for months. It wasn't until now that I needed to edit it. It came as a surprise to discover that in copying and pasting text boxes between these two applications, I lost the ability to edit them.
I have now selected the text from the original document and created a new text box in Pages and pasted the text into it. It can now be edited further if necessary.
Thanks for discovering where my error was.
The original brochure was created as an Appleworks Draw document and cannot be opened in Pages. Before I upgrade my iMac from OS 10.6.8 to Maverick, I need to make sure that I have created fresh Pages documents whenever I used a Draw document in Appleworks.
The dilemma is solved. Thank you.
