I was going to hook up my speaker outputs to my tape imputs (BIAB was up). Then got an error and could not click it away nor could I shut down and had to hit the power off button. At bottom of windows screen there is a little box that says "bbw"..it doesn't open and or does not click away. Any idea what this is? The last time I tried plugging into my tape recorder BIAB was not running and all went well. Thanks, Jerry
