disable blinking error

[Pau]

Hello,

sometimes, when I am on a window, say window 3, and I forget about it
and try to move to the next one, I assume it's 3 and then screen
complains saying

"This IS window 3 (zsh)."

for some 20 (!) seconds.

How can I disable that? Half a second would suffice.

I run into this problem at least five times a day...

thanks,

Pau
