Sometimes when moving the crosshair over a chart in my workspace I recieve the following popup error "Unhandled exception value cannot be null. Parameter name: handler"
They popup like "rapid fire" ......sometimes possibly about 100? I have to exit them by clicking the "X" on the popup multiple times. Sometimes there are too many so I have to exit Ninjatrader and restart.
This time it happened while using Market Replay
What does this error mean/suggest?
Log and trace files sent via NT
See attached screenshot
Appreciate the assistance
