from doing all these it's much easier to just delete everything(also there is a box in opera uninstaller to delete everything) and install the opera again

I find a solution with delete opera and all content using Revo uninstaller and install it again

Hello i try to start Opera but it seems running when is minimized but i can't see it as window? anyone can help? it start from today until this morning it runs OK. the system is win7 professionals. I uninstall and re-install the program
