Okay, I tried this again and while F9, F10, F11 work for sound control 
in MFE, the Dell keyboard media keys freeze MFE. I tried Alt-Tab and it 
cycled around the open apps, but when I was on MFE I had a dialog that 
said MFE had quit responding and I could Force Quit or continue. Forcing 
Quit allowed it to restart in a few seconds.

I googled the media keys and how to disable them, but have not found 
those "fixes" to work.

So I can control the volume with F9-11, I'd worry that keyboard pressing 
could crash MFE??!!
