I am trying to create the following personalized menu using the "Home Configuration" page (http://www.wrongplanet.net/modules.php?name=Your_Account&op=edithome)

When I use Mozilla, the right side of the home page (http://www.wrongplanet.net/index.php) gets heavily distorted upon submitting the changes. Examination of the "ublock" textarea on the "Home Configuration" page reveals the contents as below. Also the "Save Changes" button is missing, making it impossible to make any more changes (I had to use IE to reset the changes).

Browser info:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7b) Gecko/20040421

Contents of the ublock textarea:

When I use Internet Explorer, the right side of the home page (http://www.wrongplanet.net/index.php) is also heavily distorted, but somewhat differently than with Mozilla. Examination fof the "ublock" textarea on the "Home Configuration" page reveals the contents as below. The "Save Changes" button is present.

Browser info:
Internet Explorer 6.0.2800.1106.xpsp2.030422-1633

Contents of the ublock textarea:

<A HREF="http://www.wrongplanet.net/modules.php?name=Forums&file=search&search_author=magic"> My Posts</A>
<A HREF="http://www.wrongplanet.net/modules.php?name=Private_Messages">Inbox</A>
<A HREF="http://www.wrongplanet.net/modules.php?name=Members_Lis

-------------------------------------------------------

Note that despite IE showing much shorter contents of "ublock" textarea, the distortion of the home page does not depend on whether the "ublock" data has been submitted by the IE or Mozilla. It would appear that IE does not display the whole contents, but keeps it "behind the screen" nonetheless.

Steps to reproduce the problem (while logged on):
1. Copy three lines from the beginning of this post, and paste them into the textarea on the "Home Configuration" page (http://www.wrongplanet.net/modules.php?name=Your_Account&op=edithome), click "Save Changes" button.
2. Go to Home page (http://www.wrongplanet.net/index.php), examine right side of this page.
3. Go to "Home Configuration" page, examine the textarea and the "Save Changes" button (in Mozilla).
