Xp Sp2

[Tony Smith]

When receiving a Private Message, a window opens advising that new message has been received and asking if you would like to receive it in a new window. When I check yes, the window closes and the message does not open. I can retreive the message by going to the user CP. This only started after I installed XP service Pack 2 and occurs wether or not I have the Pop-up Blocker activated. How can I open messages direct from the prompt without having to go into the user CP?
