In general it installs and runs quite nicely. Main problem I had was that I could not get into my favorite server (www.dexworld.org). After installing IE6 into the same bottle as Steam (ignoring the warnings) that problem went away. Now I just need to figure out if I can get my usb headset to work with the same and then the world will be perfect 😉
PS I am using the beta 6 version.
