[Gretl-devel] asterisk signalling changed workfile

Hi, I'm used to the behavior that there appears an asterisk behind the file name in the main window when the workfile is changed and needs to be saved. But I just applied the HP filter to a variable and saved the output into a new variable (tick box). There is no asterisk but at the same time the file doesn't seem to be saved automatically. Is this a bug? thanks, sven
