Thank you very much, Allin.
In Spain we use a comma as the decimal separator, so we export numbers that way from Excel. When Gretl is set to Spanish, the data and estimated models also reflect decimal commas. This hadn’t caused problems in previous versions of Gretl, but since last year we’ve been experiencing issues: our students send us .gretl session files and the usual icons (regression models, graphs, etc.) don’t appear.
Do you think this can be fixed, or should we instead export the data using decimal points rather than commas?

Rosa has now done that, and it's clear what's wrong. The trouble is
that the decimal comma is being used in the XML representation of a
model in the session zipfile. In itself that will be easy to fix; I'm
wondering if we can offer a repair mechanism to make existing session
files readable.
