Thank you but I am still unable to reproduce the issue.

I notice that instead of windows @a @b and @c in the Window list, you have AAA1 and AAA45, without the @ prefix. Which /window switches did you use to create AAA1 and AAA45?

Can you create a list of steps (not a video), like the steps in my previous post, that reproduce the issue for you?

I will then follow your list of steps.
