Zandronum

I just need to know if that happens with others too (and I really recomend you play windowed)

You need to enter on a server and type the say bind (mine is T) and then enter, do it all the time and wait for the server kick for the flood.
EX Now you´ll see the console command, now try to do esc to go to the menu and try to do something more, here the skull from menu get crazy and I can´t do nothing more lol...

I´m curious if that happens with others too

I just did it, the skull appeared fine for me.

But could you use the keyboard to move it up and down or select something?

Yes, i have found that every time i get kicked from a server for command flood, the skull or custom animation radically speeds up, but nothing else seems to change.

If I just bind say button, write nothing and enter, some time i´ll get muted, then a bit more I get kicked for flood.
The skull animadion speed up and I can´t do nothing more, only with alt+f4 to close zandronum O_o

When this happens i am in full screen and have full control over the menu, the animation is just strangely sped up.
