Smart Slider 2 can't select image to insert

I encourntered the following problem using SmartSlider 2. After I had created a slide show, I attemted to add a new slide to the show. I created the new slide, added a layer and dragged and dropped an image onto the layer. However, when I attempted to select the image that I wanted to display, I could select an image from the browse dialog but clicking Insert would not exit from the dialog and insert the image.

Solution

Clear Browser Cache. Press Ctrl + Shift + Delect and make the selection to clear your browser cache.

Cause

Between when I created the slideshow and came back to add a new slide, I upgraded the Joomla Core from 3.2.3 to 3.3.0.
