no, no lenses here, its not an issue for me really, i either don't have it visible or if I do i'll have it docked at the bottom.

Yeah luckily all these issues are easily fixed by moving the synth rack. Thanks for the extra info, glad i'm not alone!

My problem is that the bottom docked Synth Rack minimizes each time I add a new synth to my project.
Every time I add a new track, I have to un-minimize the Synth Rack window.  That has never happened before.

I wonder if this is due to the new Notes tab and the synth rack.
Possibly focus going to the notes editor, for adding text in the new notes tab when the synth rack is engaged to the browser.

Found another one - "Inspector" key shortcut "I" not working only on SOME files when Synth Rack is docked at the top. Moving it fixes the problem. Really losing time each day with these new issues.

Above I mentioned the Inspector shortcut doesn't work only on SOME files - turns out they're older files. If I use a template with the synth rack docked at the top all is well, but if I move the synth rack to the top in an older file the Inspector shortcut does not work.

Confirmed. Not a fix, but I keep the multidock over everything else (full screen width) so when it's open there's no inspector or browser visible. The I key works properly in track view this way.
 
I=Inspector view
B=Browser view
(nothing)=Synth view (Synth view needs a quick key. I use A)
