AS2 - some keypresses not being recognized in CS4

programming flash
1

I’m using Flash CS4, and using ANY method for capturing keypresses, only some keypresses are recognized. Backspace, Enter, and all of the letters on the keyboard do not trigger anything for me. Even using code as simple as…

on(keyPress “<Enter>”){
trace(“pressed enter”);
}

…doesn’t work at all, while code like…

on(keyPress “<Space>”){
trace(“pressed space”);
}

…works perfectly. And no, caps lock isn’t on.
