"File Modified Outside Source Editor" Warning Message

I believe I have discovered a cause of this warning in a
specific situation. I encountered this message while
using Microsoft Visual C++ .NET. The message box appears
after the "Build Solution" command is complete, following
editing of a source file using the native .NET editor.

In this case, the project and source files were stored on
a network file server. A tape backup job was running at
the time on the file server when I encountered the
warning. I moved the project and source files to the
local hard drive on the workstation and didn't get the
error message. I moved the project and source files back
to the file server after the tape backup job completed and
didn't get the warning then either.

Under Microsoft Visual C++ .NET, the window title is
Microsoft Development Environment. The window displays
the full path file name followed by the following message:
This file has been modified outside of the source editor.
Do you want to reload it?
The command buttons are: Yes, Yes to All, No, No to All.

The bottom line is that Visual Studio .NET may erroneously
detect that a file has been modified outside of the source
editor, in situations when there is a delay between the
time the file is saved and when it is actually written to
the network drive.
