 * Hi,
 * please forgive me if this has been dealt with somewhere else: I have searched,
   but haven’t been able to find help. I am completely new to WordPress.
 * I have a large site – [http://www.inter-disciplinary.net](http://www.inter-disciplinary.net)(
   some 1500 pages); The WP-dTree plugin forms the core of the navigation system
   on the left hand side of the page. It works brilliantly in every browser – apart
   from Internet Explorer, where I get the message “A script on this page is causing
   IE to run slowly”. It then gives the option to keep the script alive – in which
   case it loads the page; or if you click ‘no’ it removes WP-dTree and the nav 
   system is sunk!
 * The real pain of the problem is that it does this for each and every page you
   visit in IE – rendering the site practically useless for IE users.
 * Could some one possibly suggest how I might be able to get round this problem?
   For any help or advice I would be very grateful.
 * Warmly,
 * Rob

 * Thank you very much for the link. If I understand this correctly, I think the
   problem I’m facing is that my site doesn’t use categories at all – just pages,
   organised into Parent, Child and Grandchild structures (and at the moment there
   are over 1500 of them). So my guess is that dTree lists them all when each page
   is called – causing IE to timeout.
 * Given I can’t turn the page lists off or face losing the navigation tool, are
   there any other ways around this? I have seen some people recommend solving time
   out messages with the “setTimeout method”. Do you think this might work?
 * Warmly,

 * I don’t see how that would help. setTimeout is used to run code at some arbitrary
   time in the future. The work must still be done and IE will still choke on it.
 * A dTree of some 240 kilobytes is… excessive. I’d probably just organize my content
   in a more efficient manner, hope that visitors stop using IE or find a plug-in
   that can build the navigation asynchronously (on request).
