As per subject line. After adding several comments in target strings in the editor window, I can only edit a comment through the context (right-click) menu and clicking "edit comment". That works as expected.

What doesn't work:
- In the ribbon, Review tab, the "edit" button is greyed out. I can make it active by going first to the comments window (I have it under my Translation Results window, so I click the "Comments" tab to make it active). The "edit" button in the ribbon becomes active.
- When the Edit button in the Review tab is active, it takes me to either the first comment in the file or to the one that I edited most recently, even if I'm highlighting another comment in a segment further down.
- Using the Alt dinkies (Alt, R, I) has the same effect as the above point. 
- Assigning shortcuts doesn't work at all. They simply do nothing. I tried assigning shortcuts to both "Edit comments" (one for the context menu, which is then displayed there but doesn't work, and the other for the ribbon, which is similarly then displayed there but doesn't work).

My shortcut for "Add comment" works perfectly, by the way.

I've just been back to Trados 2022 to check the behaviour there. It's all working as expected.

Can anyone reproduce this behaviour or is it just me?
