This is the point in other forums where somebody would yell at you for 
not showing us enough of your code. :-)

I studied the detachInterrupt code for the 32U4 and it does just what 
one would expect: clears the enable register bit for the given interrupt 
number. You're sure you're giving it the correct interrupt number and 
not the pin number, right? If that was mixed up then every time you 
pushed the button you'd still be getting another interrupt. If it's a 
level interrupt vs edge triggered, then that would explain the hang 
until you released the button ('cause every time you left the handler 
the interrupt would occur again while the button was pressed).
