Function keys inoperative on Mac

[olderbrother]

Pressing function keys (F10 to quit or F4 to end warm-up) have no effect, whether or not I'm holding down the option key. I don't know what other function keys might be supposed to do.

I'm running Mac OS X 10.5.7. This has been a problem with Nexuiz versions 2.1, 2.5, and now 2.5.1.

I don't know if it's important, but I think my graphics card (on my iMac) is ATI Radeon HD 2600 Pro.

Thanks for whatever help folks can give me!

try holding down the fn key two keys down from option..

i havent had this issue (but i dont use my function keys now that i think about it..although the few times i have used them i think i did..now that i think about it...) but yeah, old down the fn key.

you can also go to System Preferences > Keyboard, Mouse, etc and set it to use them as standard function keys rather than use the printed function. yes, i realize that disables itunes controls, expose, etc on the function keys, and trust me, i dont like that either (i had to complain to Propellerhead because their Record app makes heavy use of that function and i am SO opposed to disabling my printed key functions.. )

also, i just type "quit" in the console or click the quit button on the menu to quit, but i have no idea what this 'warm-up' is that you speak of...
