#176 Unresponsiveness of the "Notation" and "Comment Editor" windows

[Tommaso]

As the title says it happens systematically (any time I insert a new variation or perform other "basic" operations in Scid) that:

• "Notation" window becomes unresponsive to keyboard arrows: meaning that the chessboard and the move highlighting are stuck to the same position/move (even in this case it's always possible to explore the position using the mouse when the cursor is over the chessboard).
• "Comment Editor" window becomes unresponsive to the cursor and to any keyboard key (cannot insert any text).

The problem is solved by selecting any other opened window (e.g. browser) and by selecting Scid again. If Scid is the only active window M-TAB solves the problem.

In ScidVsPC a similar problem occurred to me with some older versions and it was sometimes solved by clicking repeatedly on the Notation/Comment Editor window. In Scid this doesn't happen.

I'm using Version 4.7.4 of Scid on Ubuntu 22.04.

Using v5.0.2 the steps to reproduce are:

1. Load any game.
2. Navigation using arrow keys work. So does adding a new variation via Ctrl-a.
3. Click anywhere on the board, e.g. an empty square.
4. Navigation does not work nor adding a new variation via Ctrl-a.
5. Right-click on any empty area in the Notation window.
6. Left click on any empty area in the Notation window.
7. Navigation works again and so does adding a new variation via Ctrl-a.

It looks like the arrow key + Ctrl-a work only as long as the Notation window has the focus. To my mind, the board should respond to those key strokes the same way that Notation window does.

If you could give me a hint where to look in the code base, I can give it a shot and see if I can fix it 🤞
