Are you having this problem with any other site you visit?
If so, go to "View" and click on "Zoom."
Check to see if your browser is set to "zoom out." Firefox also has a feature to "Zoom Text Only," though I do not know if IE has that. Click on "Reset."
If the problem is only happening on this site, close your browser and delete all cookies. Also clear the browsing history. If your firewall also has a cache, clear that, too.
Then reopen your browser and come back to this site to see if that has cleared the problem.
Also run a virus scan as well as scans for malware (Spybot, Malwarebytes, Superantispyware, Adaware, etc.)
If your system is clean and none of the above has helped, please provide the following information:
The screen resolution you are using (can be found under video properties; may also be found by right-clicking on your desktop and going to properties and looking under "settings").
Your Operating System (ie. XP (Pro, with teh service pack #), Linux, etc.
The browser you are using (Firefox, IE, Opera, etc.) AND teh version number.
Any recent add-ons to your browser.
The firewall program you are using.
Any and all recent software added to the system.
Acceptance on someone else's terms is worse than rejection.
