Did you create mipmaps before saving the file?

As Mir says, Under the mipmaps heading (far right of DXTBMP screen beneath the alpha channel) untick "include when saving". What you are seeing in the preview shot is one of the lower resolution mipmaps rather than your original texture.

I have difficulty translating your words but thaaaaaaaaaaaaaaaaaaaaaaaaaaaaank you it >> works
