Quoting Crastiloowa, reply 4I can confirm your dropbox links are valid.
Not sure what you're expecting to happen, though. Do you want the portion of the map that was previously unknown (prior to casting I.V.) to go black again?
Yes, that's what I would expect to happen. For example, I never visited the wildlands, so when the spell is dispelled, it should go black. (Both the mini map and the main map)
After all, what's the point of having a manna maintenance costs, if you can cast it for one turn then dispell it, and still have the benefit of it.
IMO, I think that explored (black removed from the map) should remain. Once you know it's there, you might as well leave it on the map.
However, once dispelled you should no longer still be able to see units, build queues, etc. in the area covered by the "fog of war", unless you have a unit, city, or outpost within "viewing range".
This would mean that the effect of casting then dispelling is similar to sending out a rush of scouts to view all areas of the map at once, then pulling them all back. I think that's OK; after all, you paid most of the cost up front in casting the spell, and the residual maintenance cost seems fair (or maybe even a little low) for the ongoing benefit of seeing enemy troop movements and build queues.
