CSS & Jquery Fix!

Hello, I need 3 fixes (hopefully easy fixes) for my website. Please take a look at [login to view URL] 1. In Firefox, IE8 and IE9 - when you click on the "Features" tab at the top of the page, the Features page moves slightly to the right. You may want to click several times on Home and Features, and watch how it moves. 2. In Firefox, IE8 and IE9 - on the Features page I have some jquery that allows me to collapse/expand some text. But whenever I try to extend the text, the page moves slightly to the left. You can see a video here of the issue here [login to view URL] 3. In IE6, IE7 - On the Features page, when I try to extend the text, the Free Trial button on the right moves down with the extendend text. I want the Free Trial button to be static, not to move. I hope you guys can help. Thanks
