We've had some reports lately of users on Windows and Mac having
difficulty accessing gretl's "Command log" (an item under the Tools
menu in the main window). It seems you sometimes get a "Data error"
when trying to do this. That's unfortunate since the log is supposed
to help as a bridge between point-and-click and scripting (by showing
you the command-line equivalent of things you've done via the
graphical interface).
We think this is now fixed in the current gretl snapshots, which you can find at
https://gretl.sourceforge.net/win32/ (Windows)
https://gretl.sourceforge.net/osx.html (Mac)
https://sourceforge.net/projects/gretl/files/snapshots/ (all snapshots)
Please let us know if you try the snapshot and find that the problem
is not solved.
