Take the 2-minute tour ×  I have switched a site back to use UI
version 3, so this basically works as a 2007 site would.  I
would expect that when accessing application pages this would
use the application.master in the layouts folder. It doesn't,
how do i know this? Well i edited the application.master in the
layouts folder with  Hello World  and when i open an application
page, the edited application.master is not showing.  Can anyone
tell me what master page it is using, driving me a little crazy!
share|improve this question Is it not using the v4.master or
default.master from the GLOBAL folder? –  Colin Sep 14 '11 at

testing wasn't using the simple.master?  What _layouts page
where you using to test?  If you are interested, I wrote a
httpmodule for 2007 that would set the applicationpage master to
be what the web's master was set to, for the consistant
experience: http://www.thelineberrys.com/default-category/using-
