Capture Events Button Light not Consistent

Hi.

In the MIDI Monitors, I notice that I cannot rely upon the lit/unlit status of the ‘Capture Events’ button in order to tell if I should be receiving and seeing data in the window or not.

For example:

Both of the Monitor windows shown above are in fact active (simultaneously observed to have scrolling data), but one has the ‘Capture Events’ button lit, and one has the ‘Capture Events’ button unlit.

Offhand, this seems like a bug. Thanks.
