My EOS 10 also flashes the aperture in this situation. In Av mode
however, the shutter speed decreases to compensate.
That's because in Tv mode, you're controlling the shutter, and the
camera's controlling the aperture. And of course it can't open the lens any
further, so it flashes to tell you there's a problem.
Try manual mode, or Av mode. Those are my two favorite modes.
