Dock Fader - Attention Problem

[spoons]

PT 2018.4 Eucon 18.3

Can somebody tell me if this behaviour is a bug or a function that I’m missing.

I’m using just a Dock on it’s own. Under Assign I have Dock fader to <attentioned/selected track>.

Sometimes - and this may be because it’s intermittent or I’m somehow actioning it - when I attention a VCA I get a flashing green light next to the name in the bottom left corner of the Control screen where the attention faders details are. I then can not attention away from it. When I attention away everything else follows like the EQ and Dyn etc but not the fader. Somehow after a while I get it back and alls good until the next time.

I thought that this may be something to do with Spill but I have that turned off in prefs.

I've had the Dock for almost two years and use it every day but this problem has just started ?

Thoughts ?
