what do you mean? You want to use chrome as the default browser in flex?
Chrome is my favorite browser and I use it almost exclusively, but when I made it my default browser for Flex 3, I ran into problems. Chrome does not like the debug version of Flash Player.
So I am back to IE for Flex debugging, but intend to try Chrome again in the near future, as they keep updating it.
Its fast but the plugin warning messages are annoying and chrome always sits
on top of other windows in vista
