custom thumbnails issues

I am having two issues. The first is that for some reason scissors is not correctly reading the aspect ratio of any custom image sizes defined in function.php. WordPress imports and crops them all properly, but when I go to edit a thumbnail image (say, to keep a face from being cut off) the aspect ratio defaults to the thumbnail image size regardless of what thumbnail version I choose from the drop-down.

In functions.php

add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 100, 127 true ); // Normal post thumbnails

if ( function_exists( 'add_image_size' ) ) {
	add_image_size( 'large-thumb', 150, 150, true );
	add_image_size( 'small-thumb', 100, 127, true );
}

The second problem is that the crop function doesn’t also resize, so if my crop window was 183×183 it will simply crop those dimensions rather than cropping and then resizing.

This issue would be less acute if the resize function worked like the crop function, letting you choose which version of the image you wanted to resize.

I tried implementing the fixes in this thread but they didn’t seem to work for me.
