Does OS 10.3 support Security Mode WPA?

I'm answering my own question here because I found out something very hidden but very useful.
First of all, WPA is supported in OS10.3. Secondly, I was able to connect to a Windows based, WPA security protected wireless network. The first key was to download the latest Airport update available for your computer. I cannot recall the version number that worked for me but it came up recently when I ran software update. (I've been searching the apple updates pages but cannot find it. I think it was in Security Update 2006-007 - but run software update and look for Airport). Then, to make the connection, open Internet Connect. Hold down the option key and click on the Network drop down. This gave me a WPA-Personal option that was not there before. Initially, there was a double sized field to type an encryption key. However, it would not allow me to enter anything. I repeated the process and then got a field to enter a password. Instead of entering the password, you have to enter the encryption key.You'll have to get that from the person whose wireless network you are trying to connect to. Upon entering that I got connected. I wish I could be more specific but I can't locate the info I found to get me to this point. It was in a discussion group and I've been searching for the past 40 minutes without success. I initially found it using someone else's computer. If I find more I'll post it.
