Funnily enough, I've just got back to the computer and found that Opera has updated itself to full v10 - unasked and unannounced until I restarted it!
hmmm, mine still says that 9.64 is the most up-to-date version. Questions for you users that experience opera crashes/freezes. Are you able to forcefully terminate the program through task manager? I cannot; the memory does not get released back. Sometimes, Opera crashes because of Adobe, but I have always been able to restart it right away.
