Hi, we already talked on this forum about 'focus' problems with cellblock. I think many issues have been resolved, but there is still a problem in In-Line mode: [jit.cellblock] outputs (again) the content of the selected cell at the moment it -looses- focus.
See this patch. I include a possible workaround, let me know if there are better ones. And that would be great to fix the cellblock if it's a bug, not a feature, as I think.
