ChartControl.ChartPanel.MouseMove += new System.Windows.Forms.MouseEventHandler issue

I have a strategy that tracks the Y axis of the mouse pointer with ChartControl.ChartPanel.MouseMove += new System.Windows.Forms.MouseEventHandler

Everything works fine if I open a brand new chart. Anytime I reload ninjascript it appears my MouseMove is no longer tracked and it stops printing to the screen. The only way i can fix it is if I close the chart and open a brand new one.

I am handling it in OnTermination().

Any ideas?

Below is the sample code if anyone can help

You need '-=' instead of '+=' to remove the handler in OnTermination.

Travel Well
