Hi Brian, I can't seem to find the scroll wheel hole. Can you please post a screenshot of how your MoI window and Nodeeditor dialog window are arranged with the approximate location of the hole marked?

I'm testing with this version: nodeeditor.v.1.0.rc3.2018.03.09

Does your version possibly generate some additional HTML elements that are positioned on top of the node editor's main <canvas> element?
