TaskPaper 3.3 (216)
OS X 10.10.5
When I click on a task to mark it @done, TaskPaper scrolls to wherever the cursor happens to be. This is often outside the portion of the document visible in the window, and the view jumps away from what I was looking at when I clicked. This is annoying, as I then have to scroll back to where I was.
This is similar to the bug reported here,
except that the scrolling is to the cursor, not necessarily the top of the document.
