Even the FancyApps page itself contains the error mentioned below. If you visit using Internet Explorer 9, for example, follow these steps: Go to Internet Options > Advanced > Disable script debugging (Internet Explorer). Then click on the YouTube (iframe)-link and close the movie. You'll see the following error message displayed:
Line: 1 Error: '_flash_removeCallback' is undefined
Any suggestions on how to prevent this error from occurring? Thank you in advance!
