Hi Fred,
Your new 32 bits slimjet appimage doesn't work.
With Xenial 32 bits, it, simply, destroys the task bar ! I had to shut down by writing poweroff in the terminal... But it is not a problem : I did this frugal install just to test your appimage.
I understand perfectly it is very dificult to build something in 32 bits without having a 32 bits computer to test the work done.
Thank you for your instructions to delete slimjet in the menu. It works.
