The tool tip that appears when hovering over an item in the PathFinder lingers for about 8-10 seconds and cannot be dismissed by clicking or double clicking on it. Zoom or refresing using F5 also does not help. Pressing the Escape key also is of no use.
Is there a way to dismiss it or some setting for the duration for which it appears. I looked through the Options dialog but did not find any.
Meanwhile, I figured out that moving the mouse over another PathFinder item like a Reference Plane and further quickly moving out the mouse into an empty space in the graphics area dismisses the tooltip balloon in question.
