Frame navigation issue when using arrow keys -- selection not updating properly?

[CheeseCube312]

1. What am I trying to do?

• Navigate the frame selection grid using the arrow keys
• go from one image to the next

2. What is the issue?

• when i switch between columns, i.e. right- or left- arrow keys it works. the red outline goes to the next image, the selection updates the main window
• when i switch between rows, i.e. up- or down- arrow keys it doesn't work. the red outline next image but the selection does not actually update the main window

3. Notes:

• if I use the up/down keys to navigate to another picture (let's say from image in row + column A1 down to row C1) the red outline moves but the actual main window does not update. But if I then try to move the red outline from column C1 to C2 using the right/left arrow keys it doesn't do that. The outline jumps back to A1, moves to A2 and updates the main window with picture A2.

4. Suspicion:
   I suspect that for some reason the right/left arrow keys properly update the state but that the up-down ones leave the selection stuck on a stale one. Just as suspicion, am not a programmer though, only created some small tools with heavy copilot assistance. Just reminds me of some issues I had with those.

only left/right arrows are bound to previous/next image navigation by default (any time, even without focusing on the contact sheet grid), it's by design, to jump to any picture out of sequence just click on it
