Forums Connection Issues does not attempt connection to proxy server

The proxy functionality works with the mirc I installed in to "~\Documents\mirc765\mirc\mirc.exe" but not with the one installed to "c:\program files (x86)\mirc\mirc.exe" with portable option disabled.

I am connecting to 127.0.0.1 on port 12345

It doesn't look like the connection attempt is blocking. It is a very rapid Unable to Connection error message.

I disabled Avast protection for 10 minutes during the test.
