Thanks you Luis. I was told else where that there are problems with the GPS Hydro Polygons and compiling them and all that so I will not use them if I don`t have to.

That is great. Thank you ever so much.

Ok so that clearly did not work. lol. I just change a 1641_Pts_Hydro_Generic_Ocean_Perennial polygon to a GPS_Hydro polygon and got land.

So if I use the HGX poly around my island rather than the HPX poly, this would work out just fine, ever better on a performance angle?

I am following a tutorial "Terrain_Design_for_Flight_Simulator_X" and towards the end the Author talks about using GPS Hydro Polygons. I have read the piece over and over but I am still lost. I think the bits I am missing are actually, what are GPS Hydro Polygons, and what are they used for. Any clearing up on these questions, would be greatly appreciated. Thanks :)

Manifold tool bar: Does not work on my win7 64 bit explorer browser. I think I read somewhere that it was no longer supported. Is there another tool bar or software out there that I can use that will carry out the exact same functions as the Manifold tool bar? (One example of the Manifold tool bar feature that I am looking for is: The Manifold tool bar will cache the images that SBuilderX will display) I need something that will do that. Any help would be greatly appreciated. Thanks
