In MATLAB R2025b, in the Editor, I can't get the split screen option to work at all. In R2024b and R2025a I can right-click on my code, select Split Screen | Top/Bottom, and the screen is split. Alternatively, I can select VIEW | Split Document | Top/Bottom, and I get the same thing. In R2025b these methods don't seem to do anything for me. It's not split and there are no error messages. However, if I open the Design App and go to the Code View, the split screen works ok.
Are there any settings that would affect this? Does anyone else have this issue?

The trick for R2025b appears to be "undock editor". The screen will be split in the undocked session.
If you then dock the editor again, the screen will continue to be split. However, if you click "off" for screen split then you cannot get the split back except by undocking the editor again.

I reported it as a bug. Mathworks replied to me that they knew about it and R2025b Update 1 included a fix for it. However, I updated to Update 2 and I still had the problem. I don't know if that means it worked in Update 1 and broke again in Update 2 since I don't think I can downgrade to Update 1.

It didn't work in Update 1; I tested it.
