Excessive scrolling

[dnanian]

Thanks, delosh -- we like it too.

The problem with the scroll arrows is that, on some machines, it takes longer to send the data than it does to get the "up click" back to the server. It then starts sending lots of updates and our input thread doesn't get a chance to run.

I'm looking into this problem and hope to have a solution in the future... sorry for the occasional hiccup in the meantime!
