Freezing cursor problem

[Carly]

I have a Waveform Chart with a moving cursor where the x-axis is time and the y-axis represents various analyzer readings.

At random times, the cursor leaves a marker at a specific point but also continues its regular movement across the chart. This time point also coincides with an offset error in my analyzer readings, so I would like to understand what could cause the cursor to split and become frozen like this.

(by the way, I am using Labview 5.1!)

Are you certain that you are using a Waveform Chart. Charts usually don't have cursors. Sometimes people use graphs as charts so that they can get added functionality. If that what is happening, there might be something odd in the code of it that actually creates more than one cursor or a mark of some sort.
