GetMouse does not work for reporting mouse position

[ppebb]

This functionality works fine in C, but when using dotnet curses you do not get the proper position of the mouse, it is all 0, 0. If you check the actual return value of GetMouse it is -1.

Both this and this (if you add a printf for the escape code) give the correct position.

        public static void Main()
