I've been having a strange display problem with the ARC function to create better looking checkboxes and radio buttons. I originally thought it was just my addon but it seems to happen in any table with lots of buttons or checkboxes.
Attached is a screen shot from the per-character display table from the admin section of Character Information. Notice the unhidden checkboxes on the left side of the image, these represent the radio buttons on the right side of the table, the "clean" buttons still work but it is very annoying in large tables.
It only seems to happen with IE, as Firefox does not have the issue (big shocker there I know)
