Here is my problem.
My .graal/.nw files aren't associated with the graal.exe, so I go to add them (open with) and when I select graal.exe it disallows it for some reason. It's because in the program list I already have Gani Editor and Terrain Editor, and it seems to not ant to add a third...
If I double click them from a folder, they will open. If I try and open them from RC it doesn't have a program listed to open it with.
