CPU Mining doesn't work properly. No accepted shares through CPU. Only GPU works as expected.
After 2 hours run time i can see the following:

It could be that blocks are being found before you receive the next one. It appears that your CPU hashing a rather slow which is understandable for a 2.3 Ghz processor. But pay close attention to your accepted to rejected ratio on your GPU; with that high of a rejection rate, either something is happening with your network that is causing it not to send at the right time. If this happens, the work will go stale and be rejected.
There's a number of reasons why the work could have been rejected but I don't think that the miner itself is one of them.
