The User-Agent Switcher extension Opera is good temporary remedy until they fix Opera.

You just right-click in a web page, highlight User-Agent Switcher and a list of web browsers pop up. If you click on Google Chrome, it will re-open that page using Google Chrome's code, right inside Opera. This is great because you don't have to use a different browser.

There is a launcher.exe executable in the Opera folder. In the 33.0.1990.43 folder (also in the Opera folder) is a opera.exe executable. Which executable should I use to run Opera? I'm asking this because when I installed Opera, the Opera shortcut was placed on my desktop that pointed to launcher.exe. When I tried to use this shortcut that the installer put on my desktop I get this window: http://imgur.com/gm1zzYd . However, if I navigate to the opera.exe in the 33.0.1990.43 folder and use that executable, the Opera browser opens just fine. Can someone tell me why the shortcut that the installer placed on my desktop that points to launcher.exe does not work or gets that out of memory message?

I have had this problem on Windows 7 Pro 64-bit. I am now using Windows 10 Pro 64-bit and have the same problem. I have 8GB of RAM and all my other browsers (Firefox, IE) open with no issue.
