// Description:
//      A HelloWeb2 applet displays an environment-selected message 
//      and allows the user to drag it around with the mouse.
//
// Usage:
//      Applet tag parameter "message" gives message to display.
//      Requires window sufficiently large to display selected
//              message, starting at position (125, 95).
//      Responds to click-and-drag operations on displayed messages.
