 * Hi All,
 * Having a bit of an issue. Im sure its something Im doing in my theme as it seems
   to work for themes that arent created by me!
 * When I add a widget, normally it then shows the options, but it just appears 
   blank until I save it, then options appear.
 * Also, when I add a new custom field to a post, if i click the “Add Custom Field”
   button to save it, nothing happens. If I then click the “Update” post button 
   the custom field appears twice.
 * Any chance someone can spread some light on this?
 * Phil

 * Thanks, what page should I check? The pages where the issue is? i.e. the page
   where I write my post and edit the widgets?

 * Pretty sure its to do with my code in functions.php
 * If I remove some of it, it works, if I put it back and remove the other stuff,
   it works. But not all of it :S

 * I;ve fixed mine now – rewrote my functions.php putting all of my generic wordpress
   calls for thumbnails, menus and sidebars in one php declaration.
 * Is yours fixed now or do you need a hand isimpledesign? Recon I might have a 
   solution if I can see all of your functions.php code?
