I just upgraded to Omnigraffle 6. Everything seems okay, except the canvas window view randomly jumps from wherever I am working to the upper left corner. Additionally, if there is more than one canvas, it jumps to the upper left corner of the canvas that is listed first in the canvases pane. It appears to happen even when I’m touching neither the keyboard nor mouse. I am using a MagicMouse, so I was thinking maybe it is a gesture or something. I disabled MultiTouch, but it keeps happening.
