I actually like that - just to confuse the issue. ;)2) When you mouse out [sic] of the menu without selecting anything, the menu doesn't pop closed - it just stays open forever
"Sic" is Latin for "thus" or "just as" and is used to mean that while you recognise there is some kind of error in the text you are quoting (usually spelling), you are nonetheless quoting the text intact. Using "sic" and editing the text is incorrect usage - not to mention some would consider editing their quoted text arrogant and rude regardless.
In any case, "mouseout" is the correct term for the event generated when the mouse moves out of a ui element. "Mouse out" is just a description of what you do to generate that event.
