I just found I cannot open any doc. or .xls file from Windows
Explorer into Word or Excel (OS: Windows XP, SP2). The same files
will open from within Word or Excel. When trying to open a file, Word
(or Excel) opens normally, but no file is loaded. The file types in
the Folder Options of Windows Explorer are set correctly; rebooting
computer did not help and repairing the installation of Office 2003
did not help. The same problem occurs when trying to open an attached
.doc or .xls file from within my e-mail program (Eudora
6.2) but that program is not at fault because even newly created
files in Word or Excel will not open from within Windows Explorer. My
O.S. and Microsoft Office have been running normally for more than 2
years and the problem has started only within the past month.
All help will be appreciated. Thanks.
