Hi,
I searched the web today and found a few complaints with this issue at least here in Germany, which all accrued yesterday. One guy already reported it to Amazon , will see what comes out of it.

As to Vista, I am using it with my old secondary Acer TravelMate, which I will keep for nostalgic reasons till it falls apart.

Hi,
When I try to login into my Amazon Instant Video account via Opera, I get a warning from "Opera's Fraud and Malware Protection".
Interestingly, I got this message for the first time yesterday, after I reinstalled a Vista-machine and wanted to set everything up. I don’t get this message from Opera, if I login to Amazon Instant Video from a Win7/Win8.1 Computer(s).

Specs, affected PC
Opera: 28.0.1750.40
System: Windows Vista 32-bit
Anti-virus: Norton Internet Security

Thank you in advance for any answer.
