Last 3 versions have not worked for me.  I had 1.3.4.3, and it worked great, but 1.3.4.7, 1.3.4,6, and 1.3.4.5 all don't work.  When they launch, everything looks good, but they NEVER start bfgminer.   I get a dos box momentarily that just flashes away, and then CGwatcher says it couldn't start/communicate with bfgminer.  Since 1.3.4.3 is not posted on your site, I had to go back to 1.3.3.3, which works fine.  I tried again going back to any of the above and can repeat the problem.
