I'm running bfgminer-3-10-0-gridseed on  a Win7-64bit Ultimate machine. Only 15 of my 20 miners show up, is this a known problem? Is there anything I can do to fix it?

Also, how do I make the command prompt window bigger? with 15+ devices, I can't see much of the logging of the accepted shares etc. Thanks.

Edit: NM, all the devices are there, I just had to scroll. But I still can't figure out how to make bfgminer window bigger
