Well this lab is certanly putting my system through its paces.
The latest is something that only happens in j 902 and j 903. j 901 and before
is unaffected.
When you get to chapter 2 section 4 of 'J by point and click' a plot window
opens up. Everything displays properly, but although you can type into the
terminal window, nothing will execute and the j application has to be force
quit.
When the plot window first opens a 0 shows up in the terminal window, followed
by the 3 space indent on the next line. After that whenever you click on the
plot window an additional 0 is added one line down
right on the margin. Clicking back and forth between the terminal and the plot
window just adds more of these zeros.
I thought that it may have something to do with the {{ }} issues that R.E.Boss
has been experiencing recently on a different thread so I tried adding lines
around the plot command in the .ijt file but that did not seem to make a
difference.
I have also found that if you have debug activated that a plot command will
cause 0's in the terminal window, but this does not lock up J.
Overall a bit of a concern as 'J by point and click' is a really good intro lab
and having it result in a force quit for a new user is problematic.
Any suggestions would be welcome.
Cheers, bob
