Usually, I use two displays for efficient work. When I disconnect my external screen and continue working on my laptop; if I forgot my Opera windows on the extended desktop (it does not matter whether I exited Opera or not, they will always open on the last display they were running), they remain there and do not reset to the primary display. I need to move all open Opera windows to my primary display before shutdown or sleep. If I forget this, they are stuck on the extended desktop and are not restored to the primary display (which is my laptop screen). I love Opera very much though, this problem is really annoying... Any ideas? Did anyone else had such a problem before?
