When I went to 2.7.1, at some point one of my cgminers switched pools, and then would not switch back:

I can confirm this. At first I thought it was because I manually added a pool while cgminer was running and that messed it up, but now he's posting a similar issue. Did you add a pool like me or did it switch and fail to switch back on its own Morblias?
