Hi, one of my colleagues discovered a new bug in Gretl (official 1.6.0) in Windows, and I can see that the same thing occurs in Linux: 1- Open a time series dataset (for example data3-6) 2- Estimate an ARIMA model for one of the variables. 3- In the model window, select "File/save to session as icon" 4- In the main window, go to "session files" and click on "save session as" and write a name. 5- Close Gretl. 6- Open Gretl again, 7- select "File/session files/" 8- open the previously saved session, and 9- double-click on "Model 1", then --> ¡¡ gretl exits !! -- Ignacio Díaz-Emparanza Dpto. de Economía Aplicada III (Econometría y Estadística) UPV-EHU
