[Gretl-devel] "Changing & Saving" Session Issue

Dear Allin, Let's suppose I have a Gretl session (.gretl) with saved models. If I create periodic dummies Gretl doesn't let me save the session (the option under "File -> Session files" is greyed out). The same behavior can be verified when we try to create time index or change the sample. Is this an expected behavior?
