I appreciate this is a niche issue (since very few people use Opera!) but more as an FYI: when posting (i.e. clicking the Post button) using Opera browser, instead of refreshing the page to show your newly submitted post, the webpage tries to download a file (unknown type) titled default. Posting is still successful and you can cancel the prompt to open/save file and just refresh the page manually to see the post but obviously all is not working as it should.Like I said, minor issue and I'm using Chrome in the meantime anyway...
