Best WM6 RDP software?

[TurboFool]

I currently use something that's listed in Remove Programs as Finster869 WM6_RDP. It works well enough, and I'm mostly happy with it. But it still has a couple of minor issues, like lack of screen resolution options, leaving me with portions of the computer I remote into being completely inaccessible.

Are there any better ones available that I should be aware of? Anything that improves these issues, or includes any other improvements I might like?
