I and others are aware that beautiful 'icon snapshot' feature is still unfinished.
OK, I view an icon as a snapshot when launched from the browser like this as normal:

However when I go to some next files in the file list (previous/next file) and then come back to the same icon again in the same file list I sometimes only get a single page display like this:

I also notice that the 16x16 tab thumb preview looks odd too, since it would be better the 16x16 tab thumb just displayed the 16x16 page of the icon I'm viewing in that instance.
So to summarize, the 2 problems are:
1. The loss of 'snapshot' display when from and back to the icon being viewed.
2. The tab 16x16 thumb preview using a snapshot instead of much easily using the same 16x16 size of the icon.
