Installed 10.62 on Windows 7 Home Premium 64-bit.
The first tiny problem was that I was always asked about setting opera by default, but never saved that. So I tried to write manually Opera path to the registry. Links started to open new tab in opera but without requesting a page. Also opera still asked me about default browser.
Then I set default application for http protocol in Opera settings. It show me that system default is the path that I set in registry, I accepted.
I just opened new tab in opera or clicked some link and tabs began opening endlessly.
I deleted opera physically. Installed 10.52 (first pack I found) and get same endless tab-opening.
Then after uninstalling Opera I cleaned registry entry that was fixed manually, installed 10.62 again - same endless tab opening.
This is something like "hello Chrome?" or there are any ways to fix it?)
