Changes

# <strike>"Events that require the concept of a mouse cursor must not be dispatched (for example: mouseover, mouseout)"</strike> - humph

# "When unlocked, the system cursor can exit and re-enter the user agent window. If it does so and the user agent was not the target of operating system mouse move events then the most recent mouse position will be unknown to the user agent and movementX/Y can not be computed and must be set to zero"

# User agents may prompt for confirmation before locking, this preference may be saved as a content setting (Mentioned in class by humphd, setting would be in about:config ) mjschranz

# <strike>Figure out [[Mac Crash with Jesse's SynthesizeMouseMove change]]</strike> humph

# The ESC key should exit mouse lock. This will currently exit fullscreen, and therefore mouse lock - diogogmt

# "Once mouse lock is acquired, stop mouse events from being fired to other elements that are not locked (e.g., only fire to locked element)." Only the fullscreen element will get events.
