If you open a network folder in Microsoft Windows Explorer, and then
try to open a file in that folder, the document may open as read-only or may
return an error message that the file type cannot be recognized. For example,
if you open a network folder over a slow link, click a file such as a Microsoft
Office PowerPoint 2003 presentation, and then quickly double-click to open the
file, the file may open as read-only.
This problem occurs because Windows Explorer
locks and reads the file to extract the thumbnail that represents the document
to populate the Details window of the Show Common Tasks folder
