I just installed version 4.11.7 and the problem has gone away so either it's a bug or a new "feature" that we have to set some config setting to fix.
I am still having the annoying issue with deleting thumbs.db files which I currently have on the other install as well. I'm not sure why there is a locking issue with these files but every time I try to delete a folder I get an error about thumbs.db being in use and can't be deleted.
