I concede there might be a slight improvement in the way we now diplay variables in the GUI by providing some sort of graphical sign between the ID and the variable name, that tells you visually if lags for those variables already exist, ie something like (apologies for the poor ASCII art) 2 [ ] Foo blah blah blah 3 [4] Bar grunt 4 [ ] Baz no description Which means: Foo_1 doesn't exist yet, but Bar_4 does. I suspect the improvement would be rather small, compared to the amount of work on the GUI Allin would have to do (don't look at me, I wouldn't know where to start, but someone with some GTK experience could lend a hand). But I may be wrong. What do you think, guys? Riccardo `Jack' Lucchetti Dipartimento di Economia Università Politecnica delle Marche jack(a)dea.unian.it http://www.econ.univpm.it/lucchetti
