The APM is being constantly updated and enhanced. This may require that you update your version and also your object libraries.

Update APM version

Simply install the latest GN4 version, or the latest build of the same GN4 version.

Reprocess APM object libraries

Certain changes in APM core require that you reprocess all the APM object libraries. For example, if you are upgrading to the APM version 182 from the APM version 181 or earlier, you need to perform the following procedure, as the internal data storage in the library objects changed.

Locate the ID of the current GN4 title, and then, on the Pages main tab of Fred open at least one page (it could be any page in any edition - the page itself won't be affected at all).

In the Script Editor palette, enter the following:

RebuildLibs(<titleid>)

Example: your titleID is 1258. The command should be RebuildLibs(1258)

The software will open, and then close, one-by-one, all the objects in all the object libraries of the specified title.

Important: this may take quite a long time. During the process, you cannot use Fred for other tasks.
