This has been discused before in the scripting NGs...

That's Windows at work ;-)... The process of updating an existing file by
deleting it then creating a new file (or renaimg some temp file) with the
same name as the original is very common among apps that edit documents.

If that sequence occurs within 15 seconds, Windows treats it as an update of
an existing file. To defeat that behavior, you have to intoduce at least a
15 second delay between the delte of the old file and the creation of the
new file of the same name.
