Weird Popup Problem and Why I Love Firefox

I use Firefox 2 exclusively now, but I have noticed a weird problem for the past couple of days. When I am in WordPress, Drupal, or another tool that has a similar CMS set up, I have a problem with popups.

For instance, when I highlight a word to create a link and press on the link button, the window that appears cuts off the submit and cancel buttons. Thus, I have been blindly tabbing and pressing enter to create links.

I thought that, being so user friendly, Firefox would tell me how to solve this terrible problem. I looked in the Firefox User Knowledgebase. Viola! Problem solved.
