Not sure if this is a bug or not.
I have a plugin that has two states, one with a sprite and crop and one normal image.
The first state is a sprite. If I set it to the second state and delete the crop, its ok, but I can not go back to the sprite again, because crop is broken after setting it to the original crop.
Like the following...
<layer name="plugin" url=">/skin/sprite.png" crop="463|317|76|76" >
</layer>
set(layer[plugin].url,%SWFPATH%/skin/no_sprite.png);
delete(layer[plugin].crop);
set(layer[plugin].url,%SWFPATH%/skin/sprite.png);
set(layer[plugin].crop,463|317|76|76);
workaround is just to keep using crops even if its full width.
not a big deal really.
