I use a different one, but from what I can tell it works the same and has the same menus.
As far as setting it up, when you go into Options, it will be on "256 Colors" by default, if you do the drop down you should see "High Color (16 bit)", just select that one.
On note, if you do not see the 16 bit option, make sure your server, or computer you are RDP'ing to is set to 16 bit or higher.
(On the server, or where ever you are rdp'ing to.. Start -> Control Panel -> Display.. On the Settings tab, Color quality should be Medium (16 bit) or higher.)
I'm unsure where you are RDP'ing to, I myself run a Windows 2003 server and if I recall, I had to set it to 16 bit (I'm unsure on this part, though.. can't remember if I had to set it or not).
I've tested it several times on my sprint tp, works flawlessly so far, only thing I can't figure out is how to zoom when full screen.
Hope this helps.
