A new Google update applied on 26-May-2013 affected a lot of sites that run on flash in Chrome browser (specifically version 27.0.1453.94 onwards).
As a result, websites were not able to run more than 1 or 2 flash objects in Chrome browser. As a result Science Score site when viewed in Chrome browser did not completely display all the flash object on page load. This issue was not faced by IE, Firefox, Safari users.
This problem was escalated in the official Google product forums. As lot of websites were affected the problem was getting the needed attention from the Google Chromium product engineering group. After 3 weeks, the issue got finally resolved with a new Google Chrome update.
The new stable Google Chrome version 27.0.1453.116 m released on Wednesday 19-June-2013, fixed this problem. All Google Chrome users will see their browsers automatically updated in the next few days.
