Hi Allin and others, My gretl was crashing quite often lately when I tried to create a new script. However only today I found the crashes were repeatable. If I start the gretl without any dataset and try to create a new script either with the script button, or through the menu items (file->script file->new script->gretl script) it will crash on the 1st, 2nd, or 3rd try. Here are the first few lines of the crash reports: one type of crash with error "Segmentation fault: 11”: ----------------------------------------------------------------------------------------------- Process: gretl [32290] Path: /Applications/Gretl.app/Contents/MacOS/gretl Identifier: net.sourceforge.gretl Version: 2022b-git Code Type: X86-64 (Native) Parent Process: ???
