Sorry, Allin, I'm sending you the file in case you can take a look at it. Thanks a lot Rosa ________________________________ De: Sven Schreiber <sven.schreiber(a)fu-berlin.de&gt; Enviado: miércoles, 17 de septiembre de 2025 16:54 Para: gretl-users(a)gretlml.univpm.it <gretl-users(a)gretlml.univpm.it&gt; Asunto: [Gretl-users] Re: session object(s) could not be rebuilt” when reopening session — icons only appear on second try Am 17.09.2025 um 16:46 schrieb BADILLO AMADOR, ROSA MARÍA: Dear Allin: What happens is that when I save any icon (plot, estimation of a regression model, graph, etc.), save the session and close the program Gretl, if I want to reopen it, I get an error “1 session object(s) could not be rebuilt.”and the icons do not appears, and if I close the Gretl program and try again, the icons still do not appear. However, if I open the .gretl file, it opens without icons, and once it is open, I try to open it again, and the icons do appear, as long as I don't close the program. The file's tool instruction history says “data error.” I don't understand why this is happening. Thank you. Rosa Could it be a similar or same problem as in this earlier bug report: https://sourceforge.net/p/gretl/bugs/311/<https://urldefense.com/v3/__... ? That was never resolved because of missing follow-up inputs. Maybe we can hunt it with more success now. cheers sven
