Skype -Your computer is running slowly

[Giz]

Hello there.
I recently bought an Compaq Mini 311c-1101SA (XP,1 gb ram and N270 1.6 Atom)

It's doing its job very well,but I have a small problem with skype( 4.2 version).Whenever I pull up a chat window in the right corner besides the call and videocall button there's the call information button which highlights 2 yellow stripes.When I check it the computer icon is yellow saying - Your computer is running slowly.Sometimes it gets red and says - Your computer is running very slowly.

CPU usage is around 10 - 20 percent when browsing.

PF usage - 520mb.

Running Nod32 if that changes anything.

Of course it's a small issue but I would be thankful if someone would help to resolve it.

Thanks.

Giz.

Thanks [r4] for your reply.
Yeah,video conferencing as well as voice calls are working as expected.So I guess we could just switch to 4.1 version if needed where there is no problem with this mysterious speed measurement.

Yup, same here. And I've OC'd my mini. Video and Audio works flawlessly tho.
could it be that skype 'reads' what CPU is installed in your PC rather than it's performance?
