Graph editor freezing buttons

[DSisterson]

Is anyone else having this issue-? Whenever I separate the dimensions in the graph editor, all the control buttons along the top of the graph window freeze up. I have turn the timeline off and on again to get them working.
To clarify, here's what triggers it:
-With a layer selected, click on the motion graph view button above the timeline.
-Double-click the pink "layer translation" button on the left to view the separate channels.
-Right-click and click on "separate dimensions".
At this point the buttons all freeze. Except sometimes they don't, but if I then go "rejoin dimensions" they do. Not always but most times, after the very same actions, regardless of the project.
Turning the timeline off and on clears the problem but doesn't stop it recurring. I'm using 14.2 and this is the first time I've used the graph editor, so I dont know if it's a new problem, but I've tried reverting to 14.1 and got the same thing. I'm now back on 14.2.

Thanks for the report. We will look for a solution.
In the meantime, I could reproduce it here and found a workaround. Please try this:
After you separate the channels and the buttons stop working, double click any of the Layer Translation channels (X, Y or Z). That will show you the keyframes over that channel and, at least here, will also un-freeze the timeline buttons.
