re: "also, the Quit+Relaunch seems to often happen immediately after copying something to the clipboard
Can you be more specific about 'something'? Text from Facebook, a picture, a video clip?"
I have since realized that this particular behavior (related to the copying to the clipboard) is not facebook related. I will start a new topic on this.
Yeah, that's been my work around to Curious, but as you say, is ridiculous. Was hoping this new update would have fixed this, but alas, problem remains with History and Bookmarks.
I have step by step pictures of the issue, but not sure how to post them here for Opera to follow.
