I haven't really changed much in this update that should affect config settings, other than making the "gpu-threads" default value of 2 optional (in Settings -> Miner tab).

If you go to the Tests tab and locate the Utilities section, select "Show last miner start configuration" and click Run. You can email me this info or post it here (you can remove any worker names/passwords if you wish), and I'll look for any differences that should not be there. This report shows your config settings vs. the config settings CGWatcher used when launching the miner. In most cases they're identical, but maybe a small difference could be causing this.
