Then you should look in the SVN repository how the "refresh" code
changed.

   In Zope 2.8, refresh moves all modules starting with
   "Products.<product_to_be_refreshed>" out of "sys.modules"
   (and into a safe place) and then reimports the product.

   If there is an exception, the saved modules are restored.
   Otherwise, the ZODB is told to discard the connection cache
   when the connection is opened for the next time.

With this code, "no errors, no refresh" is impossible
(you get either an error or a refesh).

Of course, someone may have turned the refresh into a "noop".
Then, you can try to reinstate the former code and see what
happens.
