Seeming incompatibility of Meks Easy Ad Widget

I have recently added a widget plugin that will rotate and randomize a set number of ads after a delay which is set within the widget. I am using Adventurous and Safari. I have noticed that the widget works on Firefox but not on Safari and contacted the Meks team. They suggested that the problem may be in the Theme that I am using. You can visit my use of this widget at http://newsforcatholics.info - it is on the bottom right and is supposed to show two books side by side which when clicked will take you to the Amazon page where they can read about the book or buy it. The rotation of the ads does not work on my Apple devices if I am using Safari for my browser. Do you have a fix for this? Thanks for any help you might provide to remedy this.
