ponchy- What is more than likely happening is that when your customers go to your checkout, the system is seeing that they have PayPal cookies on their computer, and making them log into their PayPal account. Because if you have a PayPal account, why wouldn't you be using it? 🙂
The only way they'd get the option to just enter their credit card information would be if they cleared their cache and cookies before your checkout. That should make the system give them the option of logging into PayPal or entering their credit card.
