Sorry, it's near impossible for me to troubleshoot themes that have been so heavily customized such as yours. You'll have to retrace your edits to the theme to locate the issue you're having. Wish I could be of more help.

hello. i'm graphic designer in south korea,
and we made my church website by your wordpress theme.
We satisfied your design and themes, but there're some problems.

If you see the main index page (http://nwch.hosting.paran.com/)
or
list page of posts( http://nwch.hosting.paran.com/?cat=5
), you can see the same
margin between postbox and widget.

But if you see the post page (http://nwch.hosting.paran.com/?p=182
), the margin will quite increase than two of them.
Some users (they are using lower version of internet explore or lower resolution of monitor) can't find the widget in postpages at firstime. The sidebar gets drop to the bottom of the postbox.

I don't know what is the reason of the problem but, we gave the padding value to the postbox for reducing letter numbers of a line of writing.

And there is no problem when we see your model site of church themes.

I know it because of our settings but we can't figure out. And problem is only appear in postpage.

So, i'd love to you give me some advices or tips of problems.
