PayPal option button missing on checkout page. Help!!

[moksha]

Here goes...
due to Paypal tecnical problems with credit card payments from non-paypal users I've decided, for the moment, to accept payment only through paypal accounts. Now... on the payment module the only one set is the pp IPN (have gone through all the steps to set this up properly), but when testing and visualizing the payment method page on my site the paypal option button is nowhere to be seen. The image and text are there but no button! The funny thing is that if I activate the credit card module too, the paypal option button magically reappears together with the cc option button... Does the cc module have to be set in order to let customer pay through paypal?? I've activated PDT and optional pp account too... but what happens if someone chooses the cc payment method instead?
Please help someone, I think I'm going mad!!

If there's only one payment method, there's no need for a radio button to select it.
