Can't Get Sound In (to Windows XP program running on iMac)

[macbeginner]

Hello and thanks in advance.
I'm not new to computers but I'm very new to Macs. (about one week)
I have a new iMac and Leopard -- and they are wonderful.

I've successfully put Windows XP on my iMac, using Bootcamp. Everything works so far. The first snag came today, after I installed Dragon Naturally Speaking. Dragon asks for a sound test. ... So I plugged in my microphone to the audio in port on the back of my iMac. [ I plugged the microphone in to the "Audio in/optical digital audio in" slot ]

I spoke in to the microphone -- but the Dragon software told me that no sound was coming in.

This little microphone (KOSS m/6) works perfectly on my PC. ...
I tried to fix things by adjusting the (Windows) sound level to the highest volume, but -- according to the Dragon software -- no sound is coming in.

Is this microphone not compatible with the iMac?
What do I need to do to get my voice inputted into the computer, when I am running Windows XP programs on the iMac?

thanks again ... R

Hey R,
Is the Mic-in actually detected in Windows? Also, other than the speech recognition software, does it work in something like Sound Recorder or something?
