For View.Update to work you need:

code:

View.Set ("offscreenonly")

and then add View.Update before the delay.

The reason that it only shows link when you have something pressed is because you only told the program to do that. When you first start the program out, you have no set position, so it will not show anyways. Also, more importantly, you need to find a way to keep the position still in between press's.

If you are stuck and can't figure out how to by yourself I have included some code below.
