Instead of a general complaint, how about giving what you tried to do with what code and how it acts. Maybe there is a way to do that which you want anyway. In general, however, the API is a bit awkward to work with when it comes to getting more complicated actions from the mouse. For basic point, click and drag operations, it is sufficient. Still, I suggest you provide code with a detailed explanation of the issues you are having (giving what actually happens and giving what you intended).
