When making a call, it takes a while to show the call screen, if logged into skype

Hi,

I am with Three network in the UK. Recently i noticed that if i am logged into skype (Which i downloaded and installed from a Three link), when i try to make a normal call, after i press the call button it take around 5 seconds to see the call screen. Even though i can hear the call been placed at the background.
For an instance i can hear the other phone ringing already even though the phone is still in the call log screen where i select or type the number.

But if i exit Skype and then try to make a call it take me to the call screen as soon as i hit the call button from the cal log screen.

Is this due to a software problem, I still have the option to exchange the phone, Please advice someone As soon as possible.

Thanx a lot.:)

Can some one reply please... I have changed the mobile from the same model just make sure its nothing wrong with the phone i had. Still its the same.

So if someone in Three UK and using skype should have the same problem.

Thank you.
