OnMouseDrag issue, Event System

I am trying to move an object using on mouse drag. The event system is picking up the collider of the object and registering that it is eligible to click and drag. when i click and drag that object though nothing hapens, and the methods OnMouseDrag, OnMouseClick, and OnMouseOver are never called though the event system shows that it registers the object that the script is attached to.

One more not is that this all works in a project that I created for this game, but when I exported that project as a package to import into the main game(this is a minigame) it does not work.

The scene is identical in both instances of unity but the imported version does not work.

does anyone know what might be the issue here?

Thanks for the help,
