I am in the Todelmer Chapter of Myst V, and somehow ended up with the round tablet, not the one shaped like a house. I cannot get that tablet and I think it is preventing me from getting any further. I have tried over and over to draw my picture to get to the next telescope and it never works. The Bahro picks it up and never puts the sign on the pedestal in the bubble. I am ready to throw my compter through the window.
