By the way, Bob, I am giving a talk and demonstration of the SDR-1000 next month to the Madison, WI radio club. I am giving the talk from Boulder using VNC and phone patching my audio and the SDR audio through a speaker phone. I will not fail to mention that in only a few hours from when I mentioned this bug, not only was there discussion from hams all over the world, but there was a fix to download. Hell, you can't even get through to most help desks in that amount of time, much less get a fix! Keep up the good work.
