Mathematically I know how to calculate, and also know how to draw the rectangle by being able to track mouse position when it is

问题 I am trying to develop a HTML5 white board. I want the users viewing the board to know where exactly the presenter is pointing within the screen.

问题 It is very easy to get the position of cursor out side the form's boundary by just dragaging the mouse it sends many values to the form when ever the position changes, form the following line of code.

I've seen solutions to move the cursor position to a certain spot in the text,
