I am running SolidWorks 2011 and my computer was just upgraded from Windows XP to Windows 7.

I notice now, that in the open dialogue box, set to view details, the icons for the SW files are now thumbnails instead of the file type logo.  This..... is annoying.  If I am in details, I don't care about a microscopic preview, I want to look down my list and know what type of file it is without having to look at the file type column; I'll look at the preview in the preview pane if I want to preview it.  Is there any way to make the detail list only show the file type symbols instead of the thumbnail?  Turning off thumbnails globally in Windows does not seem to do the trick.
