Thanks for reporting this errors.

In the early days, we made an assumption that there would only be one open window which turned out to be a bad one when vscode supported split panes. This error indicates that we are trying to operate on the editor that you closed; the error itself is benign and it's safe to ignore it but it'd be good to actually add checks in our codebase to see if the editor is still open.

@jpoon : It appears to no longer be benign. When I try to switch panes and I'm using Python Interactive (vscode data science tools: https://code.visualstudio.com/docs/python/jupyter-support), I get
TaskQueue: Error running task. Cannot read property 'options' of undefined., and the pane won't switch.

This is when using a hotkey for workbench.action.focusLeftGroup.

I can't seem to replicate it using your instructions @jbrowning. Are you still experiencing this?
