Scrollbar causing content to disappear

A recent release of the Adobe Flash Player (noted in version 10,0,12,36, the most recent version) is causing a problem with older Question Writer tests that require the use of the scrollbar to display content on some pages. When the scrollbar is clicked on these older quizzes using the newer player, the content disappears and will not re-appear.
To correct this problem, you need to re-apply the theme from the most recent Question Writer 3.1 version and re-publish your quiz. The new themes have new scrollbar code that corrects this problem.
This problem first appeared on the Macintosh Flash player but appears to affect the Windows Flash Player now too. We apologize for the inconvenience are contacting Adobe to try get the problem corrected in future Flash player versions.
Update: I’ve reported this as a backward compatibility bug with Flash Player 10 with Adobe – here’s the link
