Hi Allin, gretl crashed when I tried to import from fedstl database. This is a repeatable crash, and it only happens when I select multiple series while selecting the "Spread to multiple series (MIDAS)” option. Other options or selecting single series does not cause a crash. Fred Attached is the crash report without the binary part (I hope that is sufficient) Process: gretl [47738] Path: /Applications/Gretl.app/Contents/Resources/bin/gretl Identifier: net.sourceforge.gretl Version: 2019b-git Code Type: X86-64 (Native) Parent Process: ???
