Thanks for the heads up on the documentation installer - clearly we made it too intelligent :-). Given that the docs have not yet been updated for 2.4, obviously this isn't desired behaviour - I'll fix that asap.
Regarding your 030, you will need to re-install IBrowse using that hardware... If you are using the installation that you made using your 040 then the 040 codecs and jslib will have been installed and these won't work on an 030 since they use 040 specific instructions.
