Hi there. I set up an older midi controller to work with Logic and noticed that certain keys cause the Logic Arrange window to jump in and out. Is there a way to fix this using settings somewhere or is it a problem with my M-Audio Radium49 Midi Keyboard? Here's the video I made of what's happening. Watch for a good laugh. Haha. http://www.youtube.com/watch?v=5JhFgyqEOJY

ok, fixed it. There was a midi cable coming from maschine controller into the midi keyboard. Unplugged that problem went away.
