@schonkeren I have the exact same issue and haven't been able to correct it. I use the right click option to bring an offscreen app onto my main screen because I have multiple monitors. Works for all other apps and programs, just not Opera.
Also an annoying problem in Opera when I click on a field with text like a URL, it won't select the text and removes the cursor. I have to click 3 or 4 times to actually select the info I want to replace or add to.
