Hello!
Despite saying you'd be updating the Chromium engine, you're now FIVE major versions behind...
I suspect many of the issues people are experiencing have already been addressed in later versions.
You really MUST update the core whenever a new stable is released, it's unacceptable to be MANY months & versions behind as this just leaves users with security, stability & compatibility issues. You can't call Maxthon safe & compatible if it clearly isn't!
