Hey all, I'm in the process of making my own script editor. When finished it'll have debug funcs. etc, but its still in its early stages. I'm having a problem with the menubar. I can't get it to load its new windows. E.g. If i click on Open in the File menu, the window for opening a new file should pop up.
Guess what... It doesn't.
Heres the error I get when I click on Open.
