Hi ! I contact support for this issue but maybe it will be quicker here.
If you watch the video, you see that I clicked 4 times to show>hide>show the menu. Is this a normal behaviour ?
I think I know what is happening. Could you post the project? I'll make you an example.
This project is from this ebook : http://coffeescript-for-framerjs.com/ so I can't share it.But I can create a other project to reproduce this issue.
