I am working with FusionMaps XT v3.3.1 rendering JavaScript-only maps in the following fashion:  first rendering a global map with countries, which has one linked map for the United States (showing each state). 
  
The issue I'm seeing is that when I try to render the initial map, which loads up the global map with countries, it works fine in all browsers except for IE8.  In IE8, the browser waits a few moments (about 12 seconds) and then displays the following message:  Stop running this script? A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer might become unresponsive. 
  
If I comment out the chart's rendering function call within my script the page displays normally and quickly without this message showing up. 
  
What should I do to either further troubleshoot this issue or (hopefully) resolve it?
