Since installing 2010.5 my midi through won't play unless the song is playing. While I can hit the keyboard and see the notes...or use the mouse to hit the notes on the keyboard, no sound comes out.

I'm using the VST/DXI synth and I've tried every configuration from ASIO to MME. I;ve checked and unchecked run mid thru through midi driver.... I've also gone through all the options in the midi thru box. Never had this problem before...I'm guessing it might be some kind of "operator error" , but I'm stumped and don't understand if I can see the notes play on the keyboard in BIAB, why I can't hear them.

By the way when I switch to Sonar.... I hear my keyboard without any problems.....This is driving me crazy... Any help is appreciated
