 of this from recent experience when working with the metaboxes. I, too,
 had the problem to be in need of setting the screen ID which resembles the
 ID the JavaScript uses to store/ajax the information about the state of
 the meta boxes. My first idea was to use the "screen_meta_screen" filter,
 but then I basically found out what you mention in the initial post: that
 it is not called regularly so that I could rely on it. Then I found out
 about the "set_current_screen()" function. At first I wanted to hook into
 it, but couldn't really find a good hook in there. That's when I noticed
 that I could just call the function myself, with my desired
 screenID/pagenow as the parameter - and all my problems were solved.

 have worked before, it is not necessarily a bug if it doesn't anymore,
 because it might not have been used in the intended fashion (which I don't
 know, as I'm not too familiar with the background of that part of the
 code).

 have that screen properly set in javascript and php (javascript 'screen'
 name used in setting the columns in a list or ordering meta boxes in a
 page, i am using both of them) ..

 > set_current_screen() only exists since 3.0 ...

 and set_current_screen() is WEIRD !!!

 see following lines where a string separated with a dash contains the
 content of 2 variables ... herk !

 list( $id, $typenow ) = explode('-', $id, 2);
