Audition no longer letting me use the mouse inside a audio clip (Multitrack editor)

Multitrack  clips are no longer manually adjustable - mouse cursor no longer visible in clip.      I'm using Audition v 24.4.1.3 and after the latest update a couple of weeks ago i have no cursor inside an audio clip in multitrack editor .  I can't adjust the volume envelope any longer.     Have i inadvertently turned it off somewhere?  Of is there an option somewhere to turn it on now?    It's an essential tool for one of my main jobs every week -  massaging about a hundred elements into a professional sounding radio show.   I've tried the auto ducking features but it's not precise enough for what I want to do  - and it makes too many incorrect assumpions.   Takes me about 3 times as long to get a much less professional result.

I have attached two screenshots from a multitrack editor window and you can see the yellow volume line is there, but i can't move it, bend it,  or touch it wth a mouse.   There's no mouse cursor.  If i move the mouse outside the clip it's there (With my accessibiliy options turned on).   At least prior to this I could see the mouse cursor  inside a clip even though Audition ignored my accessibility choices.    Have I missed something  or is using that Autoducking my only choice now?
