big thanks!
 
First i found it strange that the diff switched from 6.x to something like 0.00000091. Now I understand that the wallet switches from cpu channel to gpu channel... and there is a other diff. Right?

I have not found a single block the last hours (with more mhash than christian) - find it a little curious.
Strange... i tested yesterday the windows version of the miner a few minutes and found two blocks instantly.
