a text area every moment i edited dynamically the scroll bar goes to the top. i know it is not a problem with the website because it works with other browsers
there is a problem with the scroll bar of a text area. whenever it is edited dynamically the focus area moves to the top instead of holding the focus in the area of the new inserted text. even if i move it down by hand it goes up again.

here's a way to make scrolling more pleasant:
1. Start Firefox.
2. Click Tools, Options.
3. Click the Advanced icon, then look in the Browsing section.
4. Enable Use smooth scrolling, then click OK.
its already activated. My problem is that when i try to edit the text area dynamically it refreshes and goes to the top
