Geraint,
Great software btw.
No, when I get to the payment page, I enter my credit card info and click "Continue" but it just stays on the page - it never advances. No errors, nothing. Someone recently said PayPal is making it more and more difficult to pay by credit card IF you have a PayPal account and don't wish to sign in. They're biting the hand that feeds them.
Thanks for help. We really need to add the popups on event info in the Mini-Calendar module.
