(Sorry if this a duplicate, I sent it from the wrong address the first time...)
I remember similar problems when I began writing plugins. There was a way round it, which I used in
X-Valid , but that was last edited a year ago, so things might possibly have changed since then.
The solution I use now is to have all the guts of the plugin in a class, but use a separate file
for each admin page, like for Gengo . This avoids your problem altogether, means the admin page
code isn't being loaded for every site view and means you didn't just have a single massive
monolithic file to edit, which can be a nightmare when you have more than one simple page.
 http://dev.wp-plugins.org/browser/x-valid/trunk/xvalid/xvalid.php - XHTML tag balancing and
cleaning for posts and comments (1 admin page, 1 feedback page).
 http://dev.wp-plugins.org/browser/gengo/trunk/gengo - Multilingual framework for WordPress (1
top level menu, 4 submenus).
Hope they help point you in the right direction,
