Starfleet Jedi

During the last week or some I've been running into this same problem. The text field shows a scroll bar when you go below the square field provided, but every time I do, it automatically shifts back up to the top. When I type a new letter, it goes down to the text line I just typed on, but shoots back up to the very top. I can scroll by using the bar on the side, but even using the left/right arrow keys to move the cursor makes it jump back up to the top. This happens on both my home laptop and my work computer.

Any ideas?

None. I haven't been able to duplicate your problem.

One thing you might consider as a work-around is writing your posts in a text editor or word processor, and then C&P to your browser window.
