turn OFF coin generation I just recently upgraded from Bitcoin client 0.3.? to 0.6.1-beta for Mac.

In the old version I had the option of generating coins; I don't see that option here.  Activity Monitor shows Bitcoin-Qt consistently using >95% CPU.  As I understand it, CPU mining is essentially useless, so I'd like to turn it off, but still have the option to receive coins if I'm paid by someone.

Is this possible?
As far as I know the option is off by default in the new versions. To make sure you can add a line

gen=0


to your bitcoin.conf file.
