I am also experiencing this problem in chrome. I think it started after updating the plugin or WordPress.
1. the animation for seconds is not working anymore. If I check the box to stop animation it seems to work ironically.
2. When I go to new post or page. I am not able to open the media tab for inserting stuff into the WP editor. I also noticed it is not allowing me to display my themes shortcode lightbox options either.
Really like this plugin but I had to deactivate until the problem is resolved.
Has anyone heard from the developer on this issue or possible figured out the fix?
