Patches: No, you can't currently drag the image around. I know that needs to be implemented and it's not really difficult - I just have too many projects. But I'm putting it on the `to-do`-list.
GmViewer: Don't mean to insult you, but have you pointed it to the right directory where the character textures are (the selection box below the one where you choose the models)? The gm files contain just the texture names, but no path. The game sets the texture path via script, but Gm Viewer (and the tool also) needs to be directed manually. The textures for locations and such are in the main TEXTURES directory, whereas the character textures are in the CHARACTERS subdir - but obviously you know that, with all your wonderful retexturing.
I have absolutely no idea what else could be wrong, for me it works nicely with textures on everything. And the textures on characters are in no way different from any other textures.
