[Gretl-users] problem:displaying lagged variables

Hello I had to re-install Gretl, but surprisingly, when I try to add a lagged variable to the dataset, it's no longer displayed on the main screen (as it used to be in my previous version). It appears in the window "Model" for regressions though. There's no such a problem for the first difference operator for intance. Does anyone know how to get lagged variables visible just like the others ? Thanks Arnaud
