You could try upgrading to the newest version of bfgminer - 4.4.0 is out now.
You could try increasing the command prompt screen size.
left click the command prompt icon on the top left of the command prompt (the one you can double click to close the window)
Select defaults
Select layout and increase the height from 25 to 30 in the screen size section.
Click OK
Close all command prompts and reload.
On a side note are you over clocking your antminers with this command in the bat file that launches it?
--set-device antminer:clock=x0981
It will make it run at just over 2Ghash instead of 1.6Ghash
(I'm running 24 Block Erupters and 1 U1 Antminer)
