Hi Allin, Today gretl crashed quite a few times, each time while I was trying to copy a graph that I've saved to icon view and past it onto powerpoint slide. Not all copy and past crashes, just after I do some editing and then trying to copy and past. So far I have not been able to isolate under what condition it will cause a crash. Here are the first few lines of the crash report: Process: gretl [84502] Path: /Applications/Gretl.app/Contents/MacOS/gretl Identifier: net.sourceforge.gretl Version: 2020c-git Code Type: X86-64 (Native) Parent Process: ???
