I have more information.

plot puts up the dialog in qt_paintit:

  info ({.~i.&LF) 13!:12''

and then exits after the user presses OK.  The crash happens after that, so it's either back in JQt or in the JE on the next sentence.

I have tested on win10 similar to your configuration but no crash.

Can you also try turning off antivirus?

Dear Henry,

I did look into it a little, and you could do the same.  This is what I
did (in JQt):

     plot 1 2 ; 3 4 5
crash - before the crash a dialog about length error in getgrafmat.
Indeed, the arguments have incorrect length.
     load 'plot'
     open 'plot'
seems to use jzplot
     open'jzplot'
ahh, there's the source.  Look for getgrafmat.  It is:

getgrafmat=: 3 : 0
'x y'=. 2 {. y { Data
,"2 (getgrafx x) ,."1 citemize getgrafy y
)
Perhaps it dies right there.  Let's see.  Change the function to:

getgrafmat=: 3 : 0
'x y'=. 2 {. y { Data
'1' 1!:2 <'C:/JPrograms/errfile.txt'
res =. ,"2 (getgrafx x) ,."1 citemize getgrafy y
'2' 1!:2 <'C:/JPrograms/errfile.txt'
res
)

<lots of blundering around omitted>
     plot 1 2 ; 3 4 5
crash - errfile.txt has been created, containing '1'.

Thus the system crashed, presumably in JQt, displaying the dialog for
the length error.
I did what you write with the exactly same result. There is '1' in the
errfile.txt.


Try reinstalling.  If it still fails report again.  Make sure you report
you system version and JQt version.
So I tried and reinstalled j901. It still crashes.

Window 10 Pro, x64-based processor, Intel Core i5-8250U.
1.0.193 is the version of the 'plot' addon.

in About I read:

Engine: j901/j64avx2/windows
Release-e: commercial/2020-01-29T11:17:19
Library 9.01.21
Qt IDE 1.8.6.s/5.12.7(5.12.7)
Platform Win64


Thanks,
Ruda
