In Firefox, K-Meleon and other Gecko-based browsers, the table header on active.asp is about twice the height as it is on other pages. This problem occurs whenever the "Mark all topics as read" icon is displayed, because a large gap appears below the icon.
Here's the fix: On line 381 of active.asp, replace
<form name=""MarkRead"" action=""active.asp"" method=""post"">
with
<form name=""MarkRead"" action=""active.asp"" method=""post"" style=""display:inline"">
