lets just say the fix makes things look horrid in real browsers lol...
An example:
1. Make a long post as a quote.
2. Quote the quote.
3. Quote the quote again.
Now, the ie7 fix is to specify a height and width that always appear, so each box has a specific height and width it has to conform to. So, what you get is a box with scrollbars, another box with scrollbars, and another box with even more scrollbars.
The original way is, each would be embedded in the prior, no extra scrollbars as they weren' tneeded.
