I'm using version 0.1 of your DLL because 0.3 did not compile in VS2005. So, I try posting an update to twitter using spaces replaced with + signs as the standard RFC compliant way of making a POST and I've got everyting working because it posts updates without spaces you see - only I get a 401 Unauthorised when I use spaces. I've tried a hell of a lot of different methods to make a post with spaces - all fail. So, what gives with your DLL? When are you going to release something what works?
