Scrollbar up and down with IE

Hi,

Here is an issue already submited in the bug tracker.
I bump old tickets with this issue but I have no response. (Example:http://www.phpbb.com/bugs/phpbb3/13343)

So, I decided to open one more time a ticket about this issue because a lot of people are concerned as we can see in the forums support. I hoped that this issue has been resolved with 3.0.6 but it's not the case ...

Issue is very simple. With IE7 or 8 in long posts that we write on the forum, the scrollbar going crazy up and down. No way to finish the post because after this behaviour, on each letter taped, the scroll up grrr.

I checked and I have well in my overall_header this line:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

Thanks per advance
