MacPerl is doing the "cursor spin" trick right now in the background. I just launched it by 2-clicking on an existing document. The spinning ball under the camel started spinning immediately, and it's still spinning now.
What, you might ask, are the menus showing? Well, I see the following: File Edit BBEdit Window Script Help Let me emphasize: though the ball is spinning, no script is running, nor should one be. Does this description help? -Richard (command-perioding)
