Random unresponsive cursor areas (case 2931)

[jarvis]

The reason I ask, BTW, is that it appears that the buttons you have created overlap with the primary "corner" regions you have created. Am I getting that right or am I mapping them incorrectly? I'm also going to attach here an excel file that I used to create that map image. That way you can edit it and re-attach it here if you like. Never done this before--seems like a useful way to visualize the regions. (?)
