I don't notice a problem while mining, but when attacking I click and click and only some of the attacks hit. It's not bad when fighting sheep but almost impossible when fighting skeletons. I'm running Windows 8.1 on a laptop with a touchpad.

Update: In Windows 10, the setting below has been renamed. Instead, search for "Touchpad settings". In the dropdown under "Taps", choose "Most sensitive".
In Windows 8.1, search for "Mouse and touchpad settings". Find the option that says "To prevent the cursor from accidentally moving while you type, change the delay before clicks work." Change it to "No delay (always on)." The problem was worse with skeletons because you move and dodge more when fighting them, causing the touchpad to not accept clicks.
You may also need to turn off palm rejection on your touchpad.
