Dear colleagues,
I can´t do a cross-correlogram with gretl 1.9.14 on windows XP SP3 in my laptop nor with gretl 1.9.90 on Windows 8.1 in my PC, selecting two variables and right-clicking the mouse.
This is the warning (Galician language) in my PC:

Should I change any directory in Tools->Preferences? I don´t see where...
Thanks
