My experience is slightly different.
JVERSION
Engine: j901/j64avx2/darwin
Release-a: commercial/2019-12-12T16:29:25
Library: 9.01.18
Qt IDE: 1.8.3/5.12.3
Platform: Darwin 64
Installer: J901 install
InstallPath: /users/bobtherriault/j901

#. 0$4
0
#. 0$0
0
#. 0$4
0
#. 0$0
0
#. 0$4
The last line consistently crashes J with the third repetition of #. 0$4
One other quirk is that in the Jqt environment on my Mac, selecting a series of
lines creates a solid blue background (expected) then when clicking on a new
line the blue background disappears behind the j sentence but remains on the
rest of line to the right. Resizing the window removes the blue background.
Probably a repainting issue.
Cheers, bob
