That's good to know as a general rule.
The interesting thing is that I did multiple tests before posting, to make sure there wasn't something I missed.
I ran my local app as admin and then not as admin with the same results. Then, I downloaded the portable version to test some more. Not admin, then admin. Same results.
So, after reading your reply, I decided to try disabling admin from my local installation again, with my antivirus (Eset Smart Security 9) off and on.
Somehow it worked. I don't know how or why. Either way, I decided to whitelist MB just in case that was messing with it.
Thanks for the help.
