I need to disable 'file preview' feature completely.  I've tried 
unsuccessfully to set time-out to 0.   I also searched some of the archive and 
most of the online documentation without finding any clues.

The traces I am looking at are on an NFS mount over a relatively slow VPN and 
Wireshark can stall for a minute or more as it tries to read every file in the 
directory.

Thanks in advance.
