Scrolling signs on click annoyance
 

This is just a slight annoyance, and it wouldn't be very intrusive to modify the sign-scroll on click in this sense.

When the window with Graal isn't focused, and you click on the screen, a say2 that popped up goes away.

Might it be better for the recent addition of the click-scrolling on signs feature to ignore the click if the click changed the window focus?

I found this to be a problem, too. It would be great if it checked the window focus before scrolling.
