Answer 1

This is the exact scenario I am facing as well which has only recently started occurring. Both PayPal account and guest users were able to successfully subscribe and I was able to pull post data from the onApprove event for both. Now any time a guest subscribes ie uses their credit card without creating a PayPal account, the lightbox is not closing and PayPal's standard confirmation page is displayed which is no good for me as I need the confirmation of the subscription to be passed to the onApprove event. Its best to ask PayPal for assistance in this matter as its quite a serious error.
