My Drupal website has a display discrepancy between Firefox and MSIE. If you'll view the Website through both browsers, you'll see that my Google Logo is displayed differently (it shifts down when displayed through MSIE, but stays in place when displayed by FFox). This logo is displayed in a Drupal 'block'. So you must know how to get at the code within the Drupal block.
I have experimented with this problem, and I don't think this problem has anything to do with Drupal, but I think you'll need to know Drupal in order to navigate the admin panel, get to the blocks section and troubleshoot.
