Problems to manage Wordpress sites after update to v. 6.9

[Manuel Casal Lodeiro]

Wordpress seems to have done important Javascript modifications to its
dashboard, because since the update to Wordpress 6.9, many usual things
I have to do with the many WP sites I manage just stopped working with
Seamonkey! :-(((

That's a huge problem for me, because I work a lot with WP panels.

Has anybody else found these problems?

Now I'll be forced to turn to Firefox for managing them :-/

But I won't be happy with FF because the recent news I will tell in the
following message.
