Priimo2.4 takes a long time to lock on sat

It takes up to 10 min. to lock on sat. everytime i want to use the nav. ( Packard Bell Compasseo with Igo Primo 2.4 running on WindowsCE 5)
I like to know how to speed up the time for getting a lock on the sat.

Is it importand to get the first time sat lock in the open field or will any lock on the sat do?

Settings:

[gps]
port=2
baud=57600

Are you moving when you try to lock on? You should be staying stationary with a clear view of the sky.
