I use Debian Stretch 9.9 and recently managed to get ToneLib Jam to install. I was not able to in the past due to a dependency failure. The libgl1-mesa-glx currently for Stretch was not up to date. However, I added the backports repo and with the command 'sudo apt-get -t stretch-backports install libgl1-mesa-glx" the depency was satisfied and ToneLib Jam and ToneLib GFX both installed. ToneLib GFX works perfectly however ToneLib Jam crashes if I use any of the items on the Menu bar (File, Edit, View, Track or any others items on the bar will crash). Everything else works apart from the menu bar. I also got this error when running from command line ~$ ToneLib-Jam xprop: error: No window with name Tonelib Jam - Untitled exists! using this command helps 'strace ToneLib-Jam 2>/dev/null'
new version 3.9.0 works perfect in Debian now, no more crashing when using the File, Edit, View, etc menus
v3.9.9 crashes on (Arch) Linux as soon as I click on some dialogue. Debugging with strace reveals that the stucture of the config folder has changed. Deleting '~/.config/Gadwin/Tonelib Jam' doesn't help.
