Old versions did this too, but in the new version, the dialog box value is not preselected.

I can take a look at this.

If I r-click when in the lower portion of the screen, the dialog builds downward right off the screen, offscreen and invisible. Sub menus sometimes are completely below the bottom of the screen and unreachable.

Take a look at [fixed] Popup menu out of screen.

(...) Also, do we need to completely triangulate the affected area?

I don't think so (although it probably can give us better results).
Coplanar issues are present in other 3D apps too. The user tkbd had shared an article with tips that can help us to better understand the problem and try to prepare better our mesh for boolean operations: Troubleshoot_boolean_operations (Rhinoceros3D Help)
Usually, add more edges to the area being affected use to improve the result. You can try to select these faces and apply Smooth [RMB] option for that and then make a cleanup after the operation.
