I love your animation/GIF @mlib
Long click on Toolbox - Cubase - Steinberg Forums
So yes, same issue in your thread - that got a surprising and welcome timely fix (at C14.0.10). This time though, the (yellow circle) left-click part of the process just makes the whole toolbox disappear.! Poof.!
And as @Reco29 confirms, still broke… (busted from C15 initial release).
I’m going to go out with a fat ‘fingers crossed’ 
for a speedy update this time too.! 
Sorry, I don’t have Cubase 15 installed.
Ok, so just found this one again - relevant for current release
Bumpity bump…
One month bump…
Sorry but the object selection tool is still broken even with the new updates!
Come on Steinberg. Please fix this feature.
Hey.! Seems this has been addressed in the latest 15.0.30 maintenance update out today… Release notes say:-
Now, I’ve not actually checked this myself, as I’m in deep on a project right now - hopefully get a chance to update next week…
Thank. You. Steinberg. For. Listening.!
