today, I decided to make one payment using Google Chrome, and everything went well, until I tried to copy the payment page, for my records. Chrome told me that it could not display the Preview, and I had no way back, other than logging out. I logged in again, and saw that the requested payment had been entered. So, I tried to edit the amount, and tried again, and again no Preview. I, then, tried with Firefox 3.6.18, and was told that the preview would open another window, and was able to print the transaction.
