IIRC basecamp (made by the Ruby on Rails team) had this problem when google's web accelerator went click-happy and deleted a bunch of stuff. Moral: Even on a restricted site you should beware of this kind of thing. You can restyle links and buttons so one looks like the other, that is pretty much always a better solution than using one instead of the other. -Adam --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
