If you click anywhere in the screen area in preview mode, all the links are highlighted, the duration and colour used may not be idea, we can improve the overlay colour and increase the duration for which the links are highlighted.
There is also possibility with short key (spacebar) to highlight the links on screen, there is some issues with it, our technical team is looking at the problem
Thanks for the feedback, we will investigate why it is happening as it should work smoothly.
