Explorer.exe shuts down during file copy and shell restarts

WinXP Pro SP2 with all fixes up to date, except on .NET 1.0 SP2 (due to
Linksys WMA incompatible with .NET 1.0 SP3 and .NET 1.1). During file copy
and at random times, Windows Explorer spontaneously shuts down. Log:

The shell restarts and file copy is terminated. I had gotten Windows
Execution Protection error messages and switched its setting to look at
everything except Explorer. I just installed the operating system and all my
software: Office 2003, Project 2003, Visio 2003, Quicken 2005, Norton Works
2005, WinTV, iTunes, and Diskkeeper.
