Hi John,
Yes we should be constructive, I am sorry for the tone of resignation. I have written it because I still find that Netbeans has the most clean design and would really want to use it further. I had no idea that something changed in handling the bugs and in the development scheme in general. If it is of any use, I can find again the few lines in question and see why it works no more. A lot of users do not like the functionality as it leads to unnoticed modifications of source code, see https://stackoverflow.com/questions/32895522/disable-copying-entire-line-when-nothing-is-selected-in-intellij/32907749
