      Ah, 500-pixels, thanks. And thanks for trying this on your end.

      Here's my screen grab:

      2026 timeline issue copy 2.jpg

      Just to make sure I'm describing this correctly, I can manipulate the keyframe / handle, it's all those other features (outlined in red) which don't become active, as they should. So, if I quickly highlight a keyframe, and want to zero the handle angle, I'm unable to do so.

        Thanks for that, entry-newspaper.

        Try this:
        1
        Where it says 'Custom (Attribute Manager)', select 'Custom', pull the menu, and then go back to 'Custom' or try something else for a moment.
        2
        Next: Copy the Cube and paste it into a new file. Any luck then?
        3
        There is also a square on the upper right of the timeline, with the arrow pointing to the upper right. When you click it, another timeline shows up.

        Have you had any luck with any of these?

        I try to gain data here.

        Cheers

          Okay:

          1. Doesn't change anything.
          2. Also doesn't change, regardless of the project.
          3. This does work. More, below:

          So, if I create a new keyframe (regardless of the property) it greys out those tools. But the moment I move the keyframe bezier handle, it immediately brings those tools to life. Or, like you suggested, by clicking on the "undock a copy" of the timeline.

          But clearly, something is wrong. This exact same thing happens on both my M1 Ultra and M4 Max.
          Is it possible that I did something weird when I customized my pallets? But even then, I set each machine up, independent of the other. In other words, I didn't copy and reuse the custom layout prefs.

            Thanks for the feedback, entry-newspaper.

            If you think it is something you did and you would like to test this, delete the preferences.

            I have the feeling it needs to be checked by Tech-Support.

            Sorry for having no quick answer here.

              Being that it's the same issue, on two totally different machines, I figure it's more of a bug. But can I send you my custom layout file? Would that help to see if I did something weird, when I was laying out my preferred layout?
              Independent of that, do I need to open a ticket with Maxon Support?

                Hi entry newspaper,

                I can check the layout (Dropbox, Wetransfer, Google, apple or Adobe cloud only, for security reasons. Thank you), but is that problem also showing with the default standard layout? Anyway, I think it is time to check with tech support.

                Yes, you need to open a ticket.

                My best wishes

                  P.S.: As those things don't let me alone 😉 I checked again all (im-) possible options.
                  As usual, I need to try it.

                  Here is a little 10-second clip, where I can reproduce it and showcase a click later on how to solve it (fingers crossed that works for you.
                  https://projectfiles.maxon.net/Cineversity_Forum_Support/2025_CLIPS_DRS/20251021_Timeline_Activated.mp4

                  In short, rectangle selection does something, but does not fully activate it. When I click on it, all is there. Could that be the difference, why you see it, and I don't?

                  Fingers crossed that makes it work for you.

                    Interesting, thanks so much for continuing to investigate. It seems that there a number of ways to "wake up" those controls, but obviously, something is wrong; it's never behaved like that prior to 2026.
                    I'll open a ticket with Maxon, to let them do their thing.

                      I'm curious what their idea is about this.

                      All the best
