user-mapped section open

[Guest ETruss]

I just started getting this error message recently. Running Vista Home

Premium. This morning, I selected about 2GB of files to copy from one

Explorer window open on my local hard drive and dragged them to another

Explorer window which was open on an external hard drive. I started getting

this error message on several files. After just clicking on OK each time, I

closed the source explorer and then everything copied with no more error

messages.
