OK, I uninstalled Bit Defender and installed Avira and all my Opera problems are gone! Ha!

@ esteni - I myself have v12 installed already, but I assume that it would have major security issues. No?

In mean that in Windows Explorer you have the option of viewing many element of the files and folders or not. I believe BD changed mine because I am sure that WE wasn't set to Hide System Files etc.

Oh, I forgot to mention, I'm running Comodo Firewall as well for a year, without issue.

OK I'm beginning to think its Bitdefender. I noticed that it changed my folder settings to 'hide' various file types, something I always unhide. The timing would be right as well.

@ riordan - I tried v30 after wiping everything and it didn't work for me. Good luck! THE next thing I'm going to try is to go back to MS Security Essential anti virus to see if Bit Defender AV screwed something up. May I ask what anti virus you are running?

@ hiteckee - may I ask what anti virus you are running?

thanks found them.

I just uninstalled 31 and downloaded and installed Opera 30 after deleting all the references to Opera 31 in App/Data and the install folder, but the same problem. Seems like e conflict with windows7. BTW I still have Opera 12 installed and it works.

thanks but when I say nothing works in Opera I mean NOTHING. I cant even open a page to save it anymore. But my 'download folder' is my Desktop, not that cluttered.
