Hi, 
    
this is with the April 19th snapshot on Windows 10 (running in
      German without local comma), and is reproducible. 
    
- open the package list window via the button at the bottom
- search for the StrucBreak package by entering "struc" in the
      search field - I'm seeing v0.91 here, from 2021
    
- right-click on the entry, and select "view code" - after a few seconds, gretl is closed/crashing; but no message from the OS about it
Then I've retried with the May 6th snapshot - same result.
thanks
sven
