[Gretl-devel] missing options for frequency conversion quarterly to annual

Hi, the attached file is the result from compacting monthly series to quarterly. When I try to compact further to annual then I don't get any options (average, summing, etc.). But I do get the options when I try other files. Is it because gretl is particularly clever (remembering the prior compacting method)? In which case I would find a corresponding message in the dialog window useful. Or is it just a bug? thanks, sven
