Cannot always drag a div

[JacopoSciampi]

I just made a very simple project following your guide using the version 1.4.2. What I've noticed is that I can't always drag the div. The code is simple:

<div ngDraggable>Drag me!</div>

and sometimes the mouse cursor got a prohibition symbols and reset the div at it's position before. Is that an issue releated to the version 1.4.2 or what?

Since I'm using angular 4 and not angular 6/7 I cannot use the latest version since the compile gives the error "ElementRef is not generic". I've seen how to fix it in this issue: https://github.com/xieziyu/angular2-draggable/issues/106
