What's Wrong?

After interrupting a write action, the output of that action remains "sticky", it keeps getting repainted as the last action even tho many actions happened since. It should just scroll up but doesn't. And if it was a large write, this makes it very hard to see what is going on as the repaint pushes the actual activity out of sight

What Should Happen?
