Long delay at start up

Hi All,

I have DS on a laptop which sometimes does not have an internet connection. At start up I get the Splash Screen for 16 seconds (measured) when I assume it is checking the internet for updates or something. Finding no internet connection it has to wait for  time-out I guess.

This does not happen when I have the internet available, start up is quite quick.

Is there anyway I can set this to not look for the internet?

Thanks
