Just for the record, I have a12 and have noticed the same thing. It did not start out that way, but has been a recent development. For the life of me, I didn't note when it started. you would think i would know better.
I have disabled odyssey and I don't use VPN. I do have hitchhiker installed. Turning on wifi and turning it on again does seem to fix it.
I'm assuming it is a registry entry that may have been triggered by one of the "tweaks" that I have installed. I'm also assuming that to find out the cause and fix it would also be better as well.
