after "upgrading" to Opera 64 f. Windows I'v run into a severe problem.
I've been using an Anonymous-Proxy program (Tor-based) to communicate with Social Media sites to mask my actual IP-address. This establishes connection to a proxy in a chosen country and produces a so called "pac-file" (automatic configuration script) which sets the proxy-address for "system" in the "Internet-options / LAN-settings"-tab.
A "Show-IP"-service on the Internet would then report back the "fake-address" I was supposedly connecting from and the Social-Media-sites would be fooled accordingly.
To make a long story short: since "upgrading" to Opera_64 the "Show-IP"-service would all of a sudden give away my true IP-address in spite of the Anonymous-Proxy-application running and successfully connected.
In the settings-dialogue of Opera I could not find any (new) setting so far that would restore things to the old proxy settings that worked successfully until Opera_63.
Any suggestions or Opera-settings / flags that might remedy this mess??
