Fixed in Vuo version:
- Mac OS 10.11
Steps causing the bug to occur:
As mentioned here can custom nodes ... this it not really a bug, you might move this to merged, but just wanted to be sure you were aware that on smaller screens, when the custom node list is long, the warning window is so big that it outsizes the screen (screenshot on a 13" screen) and you don't access the buttons anymore.
Perhaps make the node list scrollable or write some nodes then ...
How did the result differ from what you expected?:
Close the window with the close button
