I get the occasional error below.  Is there something I don't have 
configured correctly?  Or should I just ignore this?  It is not always 
this file, sometimes it is the cache.lock file or the log.newlock file. 
  I have a mail client running on my computer and my phone at the same 
time, could that have something to do with it?
