Steps to reproduce:
1. Disable any flashblocking/ad-blocking ad-ons you might have.
2. Log into slashdot (http://slashdot.org/login.pl)
3. Go to the "Help & Preferences" page (http://slashdot.org/help)
4. Do not scroll down any and click on the "General" link under "User Info"
Expected behavior:
A box appears that allows you to change some of your general settings.
Actual behavior:
A box appears that allows you to change some of your general settings but the banner ad at the top of the screen is rendered on top of it.
Extra Notes:
This happens with any of the pop-up type settings boxes.
I've seen this in I've seen this on Firefox 3.0.1, Firefox 2.0.0.14, Chrome 0.2.149.27, and IE 7.0.5730.13.
I am running on Windows XP, SP2.
Workaround: Scroll down a bit, so that the ad is off the screen (or way at the top) before opening the options menu, or get flashblock/ad-blocking add-ons.
Bug [ 2082548 ] Cannot save User Info also deals with the drawing of the settings boxes and may in some way be related.

This issue seems to have been resolved.
I've tested it in Chrome (0.2.149.30), Firefox (3.0.3) and IE (7.0.5730.13). All showed the full options box and save button.
Note: I'm been using the beta (index2.pl) homepage. I don't know if that affects the help page but it might.
