NT8b9 Failed to call 'Add' method: Cannot access a disposed object

[gregid]

I have received the following error after switching few times between instruments:
"Failed to call 'Add' method: Cannot access a disposed object"

So far I cannot replicate it but the result of the error was that the chart was still accessible but stopped drawing new price. I had to close the chart window and open a new one for it to function properly again.

Hello,

Thank you for the report.

Unfortunately this leaves a lot to guess on what may have happened.

Was there anything specific happening at the moment or before you had noticed that may have played a role? Loading a indicator or strategy, connecting or disconnecting etc?

If you can narrow down some steps I would be happy to test this to see what may be happening.

I look forward to being of further assistance.

As I said it happened only once so far, I have noticed one indicator that aside from plots draws triangles in the panel didn't draw them. I have few charts linked together with Market Analyzer where I change the instrument and what could happen is I may have changed the instruments to quickly (before charts could draw completely).
