Dojo loading screen - problems with map when setting djconfig to false?

Hi

I am trying to implement a dojo based splash loading screen as can be seen from the below blog post:

http://www.spiffyjr.me/2010/03/03/creating-a-fadein-loader-with-dojo/


It seems to work ok apart from the fact that my map window gets resized when the site loads up and I am trying to figure out why!


I have been using the editor sample code from ESRI just to try and implement it but it seems to resize that map as well so there must be some sort of underlying problem with when the map loads.

Can anyone see from the below code why the map may not be loading up correctly?


Thanks for any help!
