The misclicking is mostly due to the fact that the targets are square images with extra padding, combined with sloppy nested tables and piles of inline elements that freak out further in mobile webkit. If you're going to use tables for layout, use them consistently all the way down — don't just decide to party like it's 1994 and throw in some line breaks. Clean up the padding to rationalize the hit targets (could even use characters like ∆ and ∇ to make them non-square).
