i've seen sites that attempt to ensure/enforce their content
 (designed to appear in a framed context) to maintain
 that frame context. i believe one recent site i've come across
 is:
   http://www.quirksmode.org/ [Crashes in Solaris Mozilla]

 for example if you go to:
    http://www.quirksmode.org/home.html

 you'll see in the header a "this page is supposed to appear
 in a frameset"

 my personal suggestion is to simply move away from a framed
 version of javadocs. i know that folks are familiar with it.
 if you've already located String.java, why bother with the
 api and package frames?? the page already tells you what
 package that class belongs to.

 today one can easily create a tree widget to navigate the
 hierarchy. such a widget doesn't need to take up much
 space either. it can be floating-like, a little like a hierarchical
 jcombobox. with xul it's even easier to implement.

 i admit though that it's not as simple as i propose because
 a hierarchy tree of the world's most famous java and open
 source apis can be fairly significant in size. still though, it's
 fairly static and can be cached.
