Need Help enabling Shifted Function Keys

I have pretty much every thing running just fine except for being able to get iSeries Client access TN5250 emulation to work correctly. I figured out how to get the F1 - F12 keys to work right based on another post I found here. How do I get the shifted F-keys to work? Every time I press a Shift F-key I don't get the key, I get a Mac OS request. Anybody else run into this?
