[OpenAFS] Strange interaction with OpenAFS and Internet Explorer 7

[John Perkins]

We're running OpenAFS 1.5.56 at our site on Windows XP SP3 systems. 
Just recently we updated Internet Explorer to version 7.

After IE7 came along, Excel spreadsheets will no longer load out of AFS. 
  Copying them to the local disk and opening works fine.  This is with
Office 2007.

Has anyone else here had similar issues and/or know of a fix for this 
situation?
