I have a shop set up with QuickPay.
Card data is entered in a pop-up window.
When card data has been entered, the window is closed programatically.
This prompts windows (I suppose) to issue a pop-up warning, asking me to accept that someone is tring to close down the payment window.
This is, by most users, seen as an error condition, and it invokes fear, disbelief and trembling fingers.
How do we kill this message and restore the user's faith in our shop?
