Problem with Input Editor

Hello,

Sorry if this belongs in Bugs, but I wasn't sure. I have just downloaded NESMaker and today is my first day using the program. I was following the new tutorial; however, the video is no longer available? I'm not sure if this is just me. Regardless, the post was on the Input Editor in the tool. I just got to the part where we are to give our player controls before the video cut out.

In my editor, the controller keeps acting erratically when I select the button to apply a command for as seen below. Is this likely an issue on my end?

Thanks,

This kind of "issue" happens when your display settings in Windows are not 100%.
Some people had the same issue.. (a high dpi problem) :

I had the exact same problem. Changed my Windows 10 display settings and is fine now. It's the setting which scales text and icons. Sometimes its set higher for bigger screens.
