I was under the impression that in this version the constant freezing had been fixed.
Running win 10 64bit and Opera still freezes 3 to 4 times a day. And, btw, every single website loads slow as molasses.
They fixed "a" freezing problem. Not made it so that no one ever experiencing any freezing issues ever. If your freezing issue was not caused by the issue that they fixed then it would not have solved your issue.

DNA-49372, Freeze on Windows 10, and it should fixed in this version.
