I bet you recently upgraded to Windows 7 didn’t you. IE8 and IE9 have both shown compatibility problems with this forum with IE9 being the biggest offender. Look to the right of the address bar and you’ll see a small icon that looks like a torn piece of paper. Click it once. The problem should go away.
Another solution is to go with Firefox as your browser… [I]
I have Firefox installed on my computer. I never use it. I like IIE9 better. A one time click on the compatibility mode icon cures the problem with this site. I have never found another site that needed it. The problem is obviously here, but the work around is simple so I don’t even think about it until someone else posts the problem.
