SSX

First off I must say that I absolutely love XPize. Now on to my question. I am replacing all or most of the default icons in XPize with my own versions (and replacing a bunch that XPize doesn't touch) and I'm having issues with certain ones not displaying properly. (example: the 48x48 size for TTF files is simply upsizing the 32x32 in stead of displaying the proper 48x48 size) I beleive I read somewhere that XPize fixes this by having the different sizes ordered a certain way in the file. Is this correct? Which files need this done to them? What order must they be in? How do I change this order? (what program should I use?) I currently use Microangelo and it has no provisions to change sort order, so it always seems to place the largest image first in the icon. I noticed some icons have the 16x16 size first (the thumbnail view in explorer seems to show this). Even one of my own icons has the 16x16 size first and I can't figure out how I did it, nor can I seem to get the order to change for others. Can anyone shed some light on this, or am I completely off base here?
