There is a
critical security bug in Adobe's Shockwave software and everyone with Shockwave installed should upgrade to the latest version.
Shockwave versions up to and including 11.5.2.602 are buggy, version 11.5.6.606 is the latest and greatest. This problem affects both Macs and Windows according to Adobe.
Rather than dig into your operating system to see if Shockwave is installed, Adobe has a
Shockwave tester page that reports on the installed version of Shockwave, if any.
If Shockwave is
not installed, the results on this page vary depending on your web browser.
