This work around adds to commandline switchs:
-l disables saving of the licence data
-M enables the pointer type "New Pointers". Using this switch will result in correct display monochrome cursors connecting to Server 2008 R2. The "New Pointer" colour cursors aren't properly implemented yet and will usually look ugly because they are converted to monochrome cursors, too.
