Fields with negative top numbers visible?

[LunchnMeets at aol.com]

Hi Everyone,

Sometimes I don't know how I would manage if I didn't have this group to 
get advice from.

My latest problem is I have a stack that seems messed up somehow. The "top" 
of most of the fields and buttons is a negative number. However, they are 
visible. I want them to be visible but I don't understand how their tops can 
have a negative number.

What could be causing this? It is only happening on one of my stacks. I'm 
using version 4.6.4 if that matters.

Thanks in advance.
