Hi, BrowserUk

Just wanted to say thanks for your suggestion to add $^E to the output. The error has occurred again and the additional information was completely unexpected, however it is totally understandable and I can now close out the issue.

Just for posterity, the full error (with $^E output in bold) is "Failed to open \\servername\sharename\INQUEUE\loadqueue.lck: Invalid argument An unexpected network error occurred".
