The loading order is *not* done alphabetically. At least not on XP and
Vista (haven't tested on Win7). It's done in the order the overlays were
installed (the order they're read from the registry with the
RegEnumKeyEx() API).

You have 15 overlay handlers installed. That means only *one* of the
TSVN overlays should not show up: the 'added' one. It should simply show
the 'modified' overlay for added items.

I just installed dropbox myself for testing. But even after two reboots,
I can't reproduce the issue. I can see all the overlays just fine (using
Win7 and of course the latest build from trunk of TSVN).
