A pop-up blocker is preventing me from launching a module.

Some organisations will have pop-up blockers activated, this may stop you accessing a course if it has been set to launch in a new window. 

Hold down the control button on your keyboard, it is labelled "Ctrl".  Whilst holding down the Ctrl key click the button to start the course and keep holding it until the course opens, this will bypass any popup blockers you have installed on your computer.
