Dag and drop help

I have 3 texts in the inventory list in the left column. On drag and drop into the main area it should change to a router icon. This is taken care of, but after it changes to a router icon it should be clickable (a user can click on the router and a popup appears)
This is the code for on release()…
// if the right shape , leave it there
if (this._droptarget == “/area66”) {
this._width = 100;
this._height = 100;
this._alpha = 100;

How do i make the router clickable on drop?
Please can anyone help me on this
