The Terrain is giving me problems

[MaDmAn_71]

I'm working on a graphical update for Civ 2,putting all different types of units and graphics together to make it even better.
I have hit a problem tho.When I put a terrain tile into the terrain file,any map I use that terrain on has the corners of the tile on.What I mean is,the tile is in a little box,yes? the main tile is ok,but it has corners on that are meant to be invisible.Can anyone help me with this at all?
Any help is much appreciated.Thanks.

Make sure that the colour is the right one. Make sure that the invisible colour and the colour shown around the main tile in the box in the lower right corner is the same. That should fix it, if you're not working on gif... Use 256 colour bitmaps instead...
