Not sure what name I'd give to this problem, but I've noticed when posting a long reply that requires the text input box to start scrolling, it will start jumping the scroll bar to the top, regardless of curser position. It doesn't do it as soon as the text reaches the bottom of the box, but has to go several lines down and also seems to be dependent on the amount of characters used. I.E. I tested this by simply hitting the enter key over and over to space down to the point of needing to scroll without typing other text and the issue didn't pop up. When you move the curser with the arrow keys or are typing, the text will jump to where the curser is, then back to the top right after. I've also double checked to make sure my scroll function on my mouse wasn't activated, and it also doesn't scroll the main window when reaching the top limit of the text box as the scroll function would do. I've seen this problem pop up in both the quick reply box at the bottom of a thread, the full reply page, and when creating new topics. This is on I.E. 8 and Windows XP w/SP3.
