When switching themes in blocks, theme stays the same I'm trying to add a block to a specific theme (garland), but no matter what theme I switch to, I'm always shown the admin theme. 

If I only have a single theme (garland) enabled, I can access the blocks I need, but there has to be a reason for this.

Edit: Discovered that this is being caused by the module "RealName" I have no idea where to look for the culprit though. Any suggestions?

Edit2: Found this explanation, but no real fix. Suggestions?
Ended up using hefox's (from Drupal comments) fix

&lt;?php
function realname_user($op, &amp;$edit, &amp;$account, $category = NULL) {
    global $theme;
  if (!$theme) return; // prevent realname from overiding theme on block pages
?&gt;


I did add in my own code as a safeguard, in the if statement, the condition that we were on the blocks page.
