While editing a non-certified PackageFile in the PackageFile Editor program, you are able to search for any phrase or character by simply pressing CTRL+F. This Find and Replace dialogue has been updated for the E-Prime 2.0 Production Release (version 220.127.116.11) to include a property called 'Look in'. This property is meant to specify whether E-Prime should search the current script window or the entire experiment for the requested phrase.
The Professional edition includes the 'All Script Windows' setting, which should search all of the script for the requested phrase. However, if you are using the E-Prime 2.0 Production Release and editing a non-certified PackageFile, this function will simply open the next InLine object or script window and will not search for the requested phrase.
Upgrade to E-Prime 18.104.22.1683 or later.
