That is a problem with the Flash plugin.

You can check for problems caused by recent Flash updates and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer
  • disable protected mode in Flash 11.3 and later
  • disable hardware acceleration in the Flash plugin
  • downgrade to Flash 11.2 or 10.3

I am sorry for the late answering.

Thanks for helping me, cor-el. I have downgraded Flash and it seems everything is ok now. : ))
