I've been playing around with the PS3 browser (latest firmware v4.31)

Flash sites like Vimeo aren't working. I get the usual sort of webpage saying your browser does not support flash, download/update it here.

The Playstation website on the 4th dec says:

"With system software version 2.50 and later, support for Adobe? Flash? Player 9 has been added to (Internet Browser) on the PlayStation 3.

You do not need to turn this setting on for the Flash Player to work. If you visit a website that has flash content, you will see a message on the PS3 Internet Browser that states "Do you want to run the plugin?", highlight "Yes" and press the button. This will allow the flash content to play."

Trouble is I don't get a message. I've tried resetting all system settings to default as per their suggestion on the same page, but still no message, still no flash content.
