Bug 1:
The PointDeviation panel can be visible but the “+” button not working.
Use PointDeviation.
Leave the PointDeviation panel in place and do something else in Rhino.
Try to click on the “+” button on the PointDeviation panel - it does not respond.
Click onthe “X” button on the PointDeviation panel. This button usually means “close” but the effect in this situation is to wake up the Point deviation panel. Next click on the “+” button and new input is requested.
When the PointDeviation panel is visible it should be possible to enter new input for PointDeviation analysis by clicking on the “+” button.
Bug 2:
Use PointDeviation
Try to change the number of curve divisions. A new number of divisons can be typed in the space on the panel but it has no effect. The current results need to be closed/canceled and the input selected again.
