Addressing WowVoiceProxy.exe issues...

[MiRai]

Even though I have it set to 'Always Patch at Startup' it doesn't seem to automatically patch... Do I need to manually click the red 'Patch these files' button even if set to always patch?

Yes.

If I do that with my current settings will I get 6535 or 6553?

You will get whichever version you've selected: If you've enabled development patches, then you'll get a dev build, otherwise you'll get the live build.

I suspect 6553 if I normally only want the most stable live version I suspect I likely I should uncheck 'Download development (test) patches' to only get 6535 but figured it would be smart to ask for guidance.

Very rarely is there an "unstable" development build, especially for World of Warcraft.

OK thanks so much!

I went ahead an unchecked dev/test builds for now and patched up.

I am still going to leave Zone Alarm firewall/AV in place because they seems to work significantly better than the ones built into windows and give me more control over things executing (as exemplified in this scenario).

I guess ISboxer users (once patched up) don't really need this thread anymore... In my case I do run my 6th account outside of ISboxer so it does still help me there.

There are some Boxers don't use ISboxer so hopefully this thread at least helps them.
