Hi I am a diehard user of opera and have got to the stage where i continue to use 12,17 knowing that sometime in the future i will probably have to accept that windows 10 is inevitable and have to look for a new browser .
Does anyone have any experience of trying to run 12.17 with windows 10 . Could i continue to do this once i have reloaded 10 or will it be lost forever.

David
