Ticket #923 (closed defect: fixed)

There is an issue with modifying a dataset in place that can cause exceptions. Here is one example:

Open Boats. Start the Add Axis plugin but don't finish it yet. Move the dialog over the image. Then select Z & 2. Press the mouse button and then move the mouse around on the image while the image is being rebuilt/redrawn. Exception thrown (below). The PixelProbe has maintained a reference to some Dataset or View data that is no longer appropriately sized.
