Our users need to find the area under a curve. We use impoly (open), and they trace the curve on an image. However they are having an intermittant and unpredictable problem where part way through their tracing, Matlab ends the trace -- as if it has read a double-click, instead of a single-click. The users have already tried tracing slower and being careful to only click once per point, but the problem still occasionally occurs.
I have been unable to locate a similar problem, let along solution, during internet searches.
Any help you can offer would be greatly appreciated.
