No, you didn't miss anything from me on this. Sorry, I'm right out of it at the moment, hoping for time to address my inbox next week. I watched the ball bounce back and forth between Oleg and Konstantin for a while, then got on with my business. If this patch is fine for Oleg, below, then it's fine for me. Certainly I'll report if I see the message now that this patch is in.
