I am attempting to replace the dummy sprite with a custom sprite. I am not the only person who has this problem which means the program is not performing as advertised. What I am getting is nothing happening in Composer Mode - the Sprite Editor disappears and only shows up in Stage Mode. Double clicking the bone does NOT open up Sprite Editor. And once Sprite Editor is opened, it does not allow the accessing of any file other than the default and "empty". This is clearly a problem with the software's functionality -as it is not functioning how it is supposed to. Even the suggested fix where someone else posted this same problem tells you to undertake steps which do not resolve the problem. The program does not open Sprite Editor when in Composer Mode.
Please advise. In the event you feel you "cannot reproduce" I will be happy to record the screen so that you can see the software consistently failing to perform as you say it should. Thanks.
