Lightbox not activated inside shortcode

Hello,

First, I’d like to thank you for developing such an intuitive tool for creating [shortcodes]. I just installed the plugin and it works fine except for a small glitch.

I’m using the shortcode to insert the URL for an image file. The file name effectively populates in the code and works in the slider. However, when I click on the displayed slide image the image opens as a new window with the image. It is supposed to open in a lightbox.

Any idea why the lightbox is being disabled in code generated by Shortcoder?
