I remember how the person who started this argument was willing to pay $200 to anyone who could complete the "First Blood" map in under 3 months. But then, as expected, they disappeared. :D
In the campaign editor, when you click on a piece of the map, it seems to be visible. I usually tested such things using a cheat for victory (or the code nwcredpill)
You can also break down a campaign into separate maps and view them with the regular editor (just in case someone didn't know).
