Macbook Pro And Num Lock Options

[minim_c]

I've got a bit of an annoying glitch with my MacBook Pro when running Finale. To input notes using Speedy entry, I need to have Num Lock switched on, but it seems that when Num Lock is on, only those keys which correlate to the numeric keypad actually work - this means that I can't save or print or do anything with keyboard shortcuts without switching off Num Lock first, neither can I stop or start playback with the space bar. Does anyone know any way to get the other keys on the keyboard working as normal while Num Lock is switched on? Or do I need to manually set these using some sort of key mapping software or just buy an external?
