HP I Paq 3715 Screen Saver Problem

I have a HP I Paq 3715, I use tom tom navigator 3 and when I have tom tom in use after some time the map dissapears and the screensaver appears, showing my photo's and the calendar, how do you stop this from happening.
I also have a display appearing every 5 mins saying " Cannot Connect, unable to connect : you have no modem entries created, and no network card present.
the option to click DISMISS is there but when I hit that the message it goes away for 5 mins then re-appears,

can anyone help.

Many thanks.

Hi,
The program that is starting is called dockware...when the screensaver start press and hold the screen anywhere and you will find a tick next to 'Start Automatically', untick this and the program will go away. Not so sure about the second problem, sounds like you have installed something that is trying to connect to the net. Go through your installed programs and try and find the offending application there.
