In previous versions of J, erroneously pressing the X in the top right of the Windows Jterm screen produced an alert box asking if you really wanted to quit. This was very useful as losing a session can be seriously annoying!
I can’t find that facility in J903 under Windows 10. I hope it’s around somewhere. I can’t imagine it’s been removed but I’ve spent a while looking, to no avail. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
