This strange problem has suddenly appeared. When I click on an excel file
(either .xls or .xlsx) in my windows directory or download an excel file from
an email attachment, or click on it in the START--RECENT ITEMS list, Excel
2007 now refuses to open; I get an error window saying that "windows cannot
find the file.... Make sure you typed the name correctly". The only way to
get to file open is first to open Excel, create a blank spreadsheet and then
open the file through the Excel menu. This is turning into a real drag, as
you can appreciate.

Can you provide a fix?
