Hi Artur, Thanks for the string untidily package! It made my research a lot more efficient. Hi Allan, and the Gretl team, I have encountered a few different repeatable crashes in the last few day. In this email I will only report the latest one. When I tried to save the gretl data, and in the "save as" dialog box, if I drag a file from the finder to the dialog box window, it crashes. The reason I do this is to save time in trying to navigate through my file system within the gretl "save as" dialog box, the same way I can open files that way. Thanks in advance for your hard work. Here are the first few lines of the crash report: Process: gretl [21815] Path: /Applications/Gretl.app/Contents/MacOS/gretl Identifier: net.sourceforge.gretl Version: 2022a Code Type: X86-64 (Native) Parent Process: ???
