i had this same problem with chrome i thought it was solved when i got opera it would load the start up and then immediately close no loading wheel just instantly closes i have 125 GBs free of 451 GB disk is at 1% andi even uninstalled AVG anti mallware cause it has been known to interfere with Opera I have also uninstalled then reinstalled Opera none of this has helped and it does the same thing load the open then close not sure what to do and really dont want to be stuck with Bing another thing is that i havent ued my laptop in about 2 weeks so it might be that some how and that also happened with chrome
