Not auto refreshing when changes occur

I am using latest version of Opus 12.25x64 in Windows 10 PRO. A few months ago I started having a problem with OPUS not refreshing without me intervening and hitting F5 when I move, delete or rename files. I thought it might have something to do with a Windows or Opus update and that it would be addressed in future updates, but that hasn't happen. Is this a known issue...any thoughts on solving this. Thank you.
