Recorder not recording - no data received and err_empty_response

I downloaded version 3.1 per the link provided and read the proxy reference.  Attempt to record SSL session (port 8181) failed with "no data received" error as before.  The proxy port was left at default 8888.  Using the same URL in Chrome (browser used in all tests) without LoadComplete recording is successful, but with a twist:  I get an alert that the SSL session is not believed to be valid due to an untrusted certificate.  I am allowed to proceed and the application functions properly.  The application will also respond on port 8080 and I used the amended URL successfully.  LoadComplete will aptly record a session on port 8080 but it appears that when I try to record a SSL session a certificate trust issue is not reported or passed through the proxy, but instead it hangs until timeout then you get the no data received / empty response error.  I shall diagnose the certificate error and try again, but this particular circumstance is peculiar in that it masks what is displayed without LoadComplete proxy being active and gives an error w/o recording whereas the same URL w/o LoadComplete active throws an alert screen and permits continuing with the session once the risk is confirmed.  This is progress, but I'm not yet out of the woods.  I'll see how this behaves in the corporate lab tomorrow.
