Assumptions about how users will interact with your UX always end up badly. I saw the "big grid" and was curious, so I hovered on the icons, moving along a line, just to get an idea of what the thing does. Doing that, I kept accidentally moving the mouse pointer off-axis so it went into the popup, and was "stuck" there, until I dragged it outside the popup again, and promptly lost track of what I had already glanced at.
