In iPhoto making a book, program freezes

Question

Program keeps freezing (spinning ball) each time I type in photo captions.
I must "Force Quit" and try again. This has happened a dozen times in the last hour.
iPhoto 9.5.1
OS X 10.9.5
Using iPhoto - Folio Template
Any suggestions?
Thank you!

If repairing the database doesn't  fix the problem as a test launch iPhoto with the Option key held down and create a new, test library.  Import some photos and test to see if the same problem persists. Does it?
If you get the same problem with the new library it could be a damaged preference pane. In that case do the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home/Library/ Preferences folder.
2 - delete the contents the following folder: User/Library/Containers/com.apple.iPhoto
3 - reboot, launch iPhoto and try again.
NOTE: For Mavericks and Yosemite,  go to your Home folder and use the View ➙ Show View Options menu to bring the this window:
where you can check the Show Library Folder checkbox.
