Can't get rid off one window

[Soulprayer79]

Hello,

after 4 years absence i'm playing EQ2 again, but there's one windows which i can't close.

Does anybody know what that is and how i can close that mini-youtube window? Maybe it's from an old mod which I forgot meanwhile? (the game was installed the whole time... ^^)

I've tried to reload the ui with /loadui and selected as well "Standard" and "Default (Blue)" but the window stays there, when I load the UI-style.
And when i click that screwdriver on the right side i get redirected to the options -> user interface window.... but there is no option for video- or youtube-configuration.

I really appreciate your help. Thank you.

Regards
Soulprayer
