Released in 1.4.3

(The "Notebook Parameters" dialog)

I understand, I'll see what I can do to make the program handle such kind of errors more gracefully, but probably it won't help you much since you won't be able to work with the notebook anyway. Unfortunately I can't make this of high priority since even after three weeks the issue has zero votes.

Hi and sorry for the late reply. Well as you know Wine is not officially supported, although I find it unfortunate that CN doesn't run with it anymore. Could you tell me the details about the problem, what is not working?
Installing Ubuntu and debugging this issue would be a kind of task that I'm afraid exceeds my humble abilities at the moment. But we can get lucky if the error messages are telling and the problem is easy to spot and fix. Thanks in advance.
