Please help! My PC died and I have to rent a laptop to finish my 4 online classes. It has Windows XP on it. I have Call Waiting because I MUST be able to know when calls are coming in so I can answer them. However, while my old computer & Windows 98 told me when I had an incoming call, this laptop with XP won't! I do NOT have "disable call waiting" checked. I searched help and everything and can't find out what's wrong. Can someone please help me??? Thank you!!!
