Logitech webcam in MSN

Hi,

Have anyone experienced problems getting your webcam to work in MSN ?
I bought a new computer for my daughter and she cannot get her webcam to
work in MSN.
She has a HP Pavilion t3050 running XP Home version 2002 with SP2 installed.
The webcam is a Logitech Quickcam 300 (drivers updated)
MSN version 7.0 (build 7.0.0813)

The webcam itself works (Verified in : my Computer/scanners and cameras)
It's only in MSN it doesn't.
She have temporarily deactivated the firewall, just to rule out that one.

It works fine in MSN on my Compaq Presario 8000 running XP Home version 2002
SP2 installed.
I also have MSN 7.0 (build 7.0.0777)

Any ideas would be appreciated !
