Has anyone tried downloading 'sit' files, or' hqx' files only to discover that Stuffit doesn't seem to be able to expand them? Instead it either does nothing, or hangs. Yet some sit files work fine. It seems like archives created with newer stuffit versions have no backwards compatibility with old versions. Unlike any other archive format like zip or rar... or maybe I am just having really bad luck installing applications. 
Would appreciate any advice on this. The highest stuffit version I have tried is 5.5.
