Opera 35

Hi all,
I use Opera in the sandbox of Comodo. Today I have updated Opera to the version 35, it runs fine outside the sandbox but it no longer runs in the sandbox. The PC is almost hung, CPU is at 50%. When I quit Opera there are several Opera.exe still running and CPU is still at 50%.
What may be happened?

I have reset the sandbox, I have reinstalled Opera. No result.

I have no issues running Opera in the sandbox when started from the widget, run in sandbox context menu, or with auto-sandbox rules. Does the problem exist after restarting your computer?
