thank you for your help

hi everyone,

When i open the karnaval.com to listen music, the radio channels are not opening. Is there anyone who can help in this matter? This problem does not exist in other browsers.

[Moved to correct forum]

Yes, the problems solved. When i enabled opera://flags/#ignore-gpu-blacklist, the download button and address bar suggestions started to work. My opera browser works normally now Thank you very much for your help.

Same problem here in my Asus N53JL notebook with graph card nvidia gt 425M, the download button and adress bar suggesions don't work when "Use hardware acceleration when available" is enabled.
