I remember a couple wd 'picon' related crashes from the J4 days. There was one
where using wd 'picon ' without creating or selecting a form would crash J
(i.e. as simple as wd'picon ',('j.exe',~1!:40''),' 0' ). But I can't imagine
that's still a problem; not since the MDI/SDI switch.
I have even vaguer memories of a crash that occured when a form was selected,
but picon specified the name of a file which did not exist. But the
circumstances were special, it wasn't as easy as wd 'picon invalidfilename 0'
(did the filename have to have spaces, with the quotes elided?). That may be a
lingering bug.
Anyway, I can't make beta M crash using picon. Can you create and send a small
transcript which demonstrates the error? Can you test it in beta N, to see if
the bug has been fixed?
