Hello, Yesterday during the Pharo Sprint I was experiencing many problems with my 64-bit Pharo Image and Pharo Sprint App. For example, whenever I clicked "Open in FogBugz", "Discuss on Discord", or "Help" in a Sprint App, I got Error: Could not find accessor for variable named "command" As suggested on Discord, I tried this WebBrowser openOn: 'http://pharo.org' and received the same error Then, after I executed xdg-open 'http://pharo.org' in my Linux terminal, and it worked without an error, *Juraj Kubelka* assumed that *ffi does not work on Linux 64-bit* and told me that I should report this issue to *Torsten Bergmann*. Also, no method comments or class comments were visible in my image. And when I tried to write and save a comment, it just disappeared. These two problems may be related.
