Does Symantec still flag it? I've submitted both 1.0 and 1.1 to whitelist but request was denied, yet treat was no longer detected according to virustotal. I hope with digitally signed 1.2 better i may expect better luck. As for guest Paypal payments, i'm afraid to enable them, since it requires switching to Business account. If you can help me testing guest payments, write me to email please.
