To verify, open the gretl console and type include StrucBreak.gfn You should see StrucBreak 0.91, 2021-07-20 (Riccardo "Jack" Lucchetti and Sven Schreiber) Or alternatively, type pkg query StrucBreak in which case you should see several lines of output, among which Package: StrucBreak 0.91 (2021-07-20) Allin Cottrell _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/

Then I guess there must be some stale StrucBreak version on your system, and somehow gretl is picking that in the GUI context. It clearly shouldn't do that, but perhaps you could try doing a file search on your computer for other occurrences of the StrucBreak.gfn file.
