In fact, in IE7 what you are using is known as the TypedURLs list
and not really related to your History at all.

Well, are they in your History? Depending on how often you add new
entries to TypedURLs versus how often your History (e.g. Ctrl-h) changes,
they could be out of synch. If the rendering of the icon depends on the
presence of the URL in your History, not having it there would explain
your symptom.

Apples and Oranges? Does Firefox use TypedURLs?

Is that still working? I had read that Favorg might have a problem with
some new implementation for favicons in IE7...

FavOrg's author did investigate the possibility of updating FavOrg to work
with IE7, but came to the conclusion that it would be a waste of time
</quote>
Oh. And this has reminded me of another possibility...
<quote>
Apparently, IE7 periodically (during "idle time", perhaps?) goes through
your entire Favorites list, retrieving and setting favicons
</quote>
Is the URL in question actually a Favorite? If so, and there is such a visit
and the host does not respond, perhaps that would be enough to cause
the Favorite's favicon to be deleted? In fact, favicons for Favorites are
also stored in NTFS stream files under the Favorites subfolder but I have
never detected those images actually being used. It has always looked
like WIP to me. I asked (repeatedly) for some clarification about
the new implementation without result.
Related to this you should also be considering whether you ever look at
the History item for the URL you have your problem symptom with.
E.g. there is known bug in IE7's History which causes the Last Accessed
value always to change. If this happens because of the rendering of the
site's favicon and an actual download for it is requested (e.g. due to your
cache-checking option being Every time I visit...) and it fails, then
similarly that might result in the deletion of the site's favicon.
You could try some of the diagnostics that I suggested to other posters
who supposedly were interested in uncovering more quirks about IE7's
favicon implementaton, e.g. Run... FileMon filtering on *fav*
Running Fiddler2 concurrently would also help make it clearer
when favicons were being fetched from the web versus from the TIF.
On top of all that I bet that IE7 still has the longstanding issue about
deleting items from the TIF seemingly randomly but I haven't checked
on this since IE6. Let's see what David Pochron is doing these days...

As for my thoughts on IE7, its caching pretty much works the same
as it did with IE6. It tends to remove files that are oldest but skips
large chunks of them and can remove many newer files as well.
</quote>
I used to use his CacheMonitor tool to understand how the TIF
was being (ab)used by IE. You could try it too to see if that's
how your favicons are going.
Good luck
