I'm having some trouble associating The Unarchiver with Zip files. They reset back to BOMArchiveHelper for some strange reason. When I went to reassociate them (via Get Info), The Unarchiver did not show up as an option on the "Open With" popup menu. If I select it using the "Other..." option, it works and the icon shows up properly. If I select "Change All...", it works - but the icon disappears and becomes a generic document icon!

I'm sure this is something weird on my end, but I thought I'd report it - just in case.
