The crop feature doesn't seem to be functioning correctly.

I position the frame over the exact area to retain, when I hit return or command-k the outer area gets cropped which is right. Then I do a Save As and choose JPEF with no recompressing plus I have to additionally choose Trim or Expand which is strange since cropping always trims something off. Anyway, if I choose Expand then the program adds a border (a few pixels wide) along the top and right side. Conversely, with Trim the program cuts away a border also on the top and right side. I can never get the exact area that I've framed with the crop tool. Is this a bug or did I do something wrong?

Am using OS 10.4.10 and Xee 2.0. Thanks for all the time you put into this program.
