My system is set up to use the Windows versions of Office apps under Parallels for all of my .doc, .xls, etc. files. This works fine. I can double-click a file from the Mac finder and the correct app will launch under Parallels. Unfortunately, all of these files show a blank default icon - making it difficult to distinguish between different types of files at a glance. This applies to existing files as well as new files I create. It seems like something is broken in the mechanism that allows Mac OS X to determine the icon to display from the associated application.
