I was excited to find GanttProject to create simple Gantt charts. It is straightforward but has enough functionality for what I need. However, it is extremely unstable. After spending two hours entering my data, it keeps crashing now, and there is no way I can open my file. In particular, when I press on a file to open, it gets stuck, uses 100% of the CPU thread, and does nothing for many minutes. Overall, it is not worth my time. I would be happy to pay a premium to have functional software, but unfortunately GanttProject does not work for me. Operating System: Windows 11.

Hello, I used your Ganttproject 2.8.11 on my 32bit debian system and it is very good. I am trying to update it to new 3.0 version. When I launch it I have this error: <Loading library prism_sw from resource failed: java.lang:UnsatisfieldLinkError: /home/XXX/.openjfx_sw.so: class ELF errata: ELFCLASS64 (Possible cause: architecture word widht mismatch). This lib is in your package .deb to usr/share/ganttproject/plugins/base/biz.ganttproject.app.libs/lib/openjfx-11.0.2.jar. Can you think to use openjfx.jar for 32bit or Ganttproject is out of 32bit support?
