Hi Filipe,

I don't suppose something similar can be done for the 14.04 versions can there ?

my "fixes" broke the automated tex output for it ...

best,

Jack

just for info : downloaded and built the 16.04 updated Cantor Version 16.07.70 on Kubuntu 16.04 - doesn't seem to work, opens a sage window : typing commands hangs it or displays nothing as output.

Only solution I got running was mathcals' suggestion here:
https://bugs.kde.org/show_bug.cgi?id=348128
The LaTeX doesn't work however (it does on the old Cantor in Kubuntu 14.04)

thanks for all the hard work!
