Thank you for spotting this. The reason for this was really hard to
track down. It turns out to be the following line in NSInputManager:

BOOL isFunctionKey = [theEvent modifierFlags] & NSFunctionKeyMask;

This used to work while the value for NSFunctionKeyMask was in the first
byte, but now it is 1<<24 and the resulting BOOL was NO.
This should be a warning to all of us to program more careful and always
use explicit comparisons for integer masks. This code does the trick:

BOOL isFunctionKey = ([theEvent modifierFlags] & NSFunctionKeyMask)
        == NSFunctionKeyMask;


Cheers,
