How to isolate MIDI to current track?

[Ronman]

I very commonly use Shift+Alt+F6 in Piano Roll view to select from the currently selected MIDI note to the end.   That used to work.  But lately, it selects within not only the current track but all tracks!  A dangerous proposition.  I haven't found anything in the manual about this.

If I select within the track view, it works as expected, but not if selecting within the Piano Roll view.

It works the way you say it's supposed to on my system.

I get the same result as OP. When focus in PRV is on a single track and no track is selected in track view, and I select a single midi note in one track in PRV, Shift+Alt+F6 selects all tracks, including audio and instrument tracks, and any notes, audio, and other events to end of all tracks.

I also get the same result as the OP

However, a workaround I have found it to bind SHIFT+END to the following CAL Script:
(do
    (= Thru End)
)

This works even if the PRV has focus and does not select tracks not in focus.

Granted, not ideal as you have to have at least one note selected for this to work.
