Description

[Marco Castelluccio [:marco]]

I'm seeing the following exception in the browser console:
> notify event 'newSource' threw an exception: TypeError: this._instrumentsPane is null

No activity for 6 years, no STRs, closing.

Please feel free to reopen if you still see the problem and you can provide STRs we could use to reproduce it.

Thanks,
Honza
