I have OSX 10.4 and everytime I try to play streaming files from windows all three of my browsers crash (IE, Firefox, and Safari). At first Windows Media Player stopped working. It wouldn't load and in the dock, all that happens is that the WMP icon keeps going up and down and never opens. So I got Flip4Mac and I have the latest version. For a while that worked well but when it updated a few weeks ago it started crashing my browser. Even when I turned off the option to convert streaming audi to quicktime it would still freeze.
