Sandbox errors on many high end flash sites

I keep getting some Sandbox errors on many high end flash sites that I visit, could there be something wrong with my browser or flash player or OS?

Could you give an example?

My own site (http://www.ecommercetotal.co.uk/) for example



SecurityError: Error #2121: Security sandbox violation: SoundMixer.computeSpectrum: http://www.ecommercetotal.co.uk/banner.swf cannot access http://mail.google.com/mail/im/sound.swf. This may be worked around by calling Security.allowDomain.
at flash.media::SoundMixer$/computeSpectrum()
at Spectrum/update()
at Mp3Player/onTimer()
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()


What does google have to do with it? :(

Sorry the error that I am getting now is

SecurityError: Error #2122: Security sandbox violation: SoundMixer.computeSpectrum: http://localhost/ecommercetotal/ecommercetotal.co.uk/banner.swf cannot access http://www.ecommercetotal.co.uk/mp3/track1.mp3. A policy file is required, but the checkPolicyFile flag was not set when this media was loaded.

Flash doesn't allow you load load certain things from other sites. Ergo, you are getting this message about a policy file.

You probably need to have a crossdomain.xml file available, google it for more information because its confusing for me to try and explain.
