ok. I thought there might be a reason. I guess something like a read-only property could be a problem if anything tries to change those. Are there other properties you know of that could be problematic? maybe before/after change properties? I think there are inhibit-* variables to avoid issues with those if they become a problem.
I am still baffled on why the unusual workaround with message-box makes it work though.
