no, opera wasn't causing any problems, i just decided on that system to remove the `growingly' obsolete software: it was my windows 7 system and i was playing with various replacement browsers, and had finally decided to use an opera-ized firefox (via extensions) as my default- though i'm still playing around and could switch to seamonkey???? (still playing with opera's mail program and haven't decided on whether to keep it or not). opera 19 is still on my system, but is looking increasingly irrelevant compared to firefox. i still use opera 12.16 on my linux, i find it faster than chomium and firefox, and security isn't as concerning on that system. so long story short ... opera 12 removed from my windows 7 for acceptance of inevitable.
on that system, antivirus is mse and webroot. additionally have winpatrol and spyshelter to harden system. problem may have come from spyshelter, though logs don't indicate this. but spyshelter can run browsers with limited user rights. this post interested me because there was some similarity in the problems. so i suggested my fix.
inversely jarodsafehouse71, if your problems only occur when opera is started, try my above suggestion. if your problems occur immediately with startup of system, you likely have other problems. you could try starting in safemode and tackle your problems from there. uninstall opera 12 to see if it was the root of your problems - if not you can always reinstall. scan your system for malware. make sure there are no updates for your drivers (or for windows in general). think about if you recently installed something new that might be causing conflicts and uninstall it to check (perhaps your antivirus just had a big, bad update?). if all else fails, it might be time for a system restore point (its so much easier than trying to figure it out, sometimes).
12.15 changelog: http://www.opera.com/docs/changelogs/unified/1215/
-- Fixed an issue where the search bar's default engine could be overridden by third-party apps.
-- Fixed a moderately severe issue, as reported by Attila Suszter; details will be disclosed at a later date.
-- Fixed: RC4 encryption protocol is vulnerable to certain brute force attacks. Due to the time this amount of requests takes, this is not a practical attack against most users.
-- Fixed: Cookies can be set for a top-level domain. In some cases, this may confuse a site's cookie handling, causing it to mistake that cookie for one of its own, and reusing it for authentication without modification. This could lead to the user's accounts being compromised on that site.
12.16 changelog: http://www.opera.com/docs/changelogs/unified/1216/
-- Opera Software recently experienced an attack on its internal infrastructure. Following best practices, Opera is replacing signing certificates in Opera with newly issued certificates. (The time window for possibly-compromised 12.15 version downloads was very narrow in time, but in principle some downloads could have been performed therein with flawed/faked certs, so Opera bumped the version to assure new clean certs would be deployed to users).
You have two separate, but related issues: putting (and keeping) Opera in kiosk and full-screen modes, and putting (and keeping) Windows in kiosk mode. Opera is an application program running on an OS, and unless you bullet-proof the OS as well, anything Opera does to protect its kiosk mode can be bypassed through the operating system... as you've noted. Either you have to block the OS from being directly called by keyboard, or you have to accept that the application (Opera) can be closed but block the user from doing anything else but reopening it. Unless you elect to use an optional software program to support kiosk operations, what you can do in Windows 7 directly is limited to disabling interactive shutdown, log-off, locking the station, and switching user accounts. http://blogs.technet.com/b/keithmayer/archive/2012/08/03/building-public-kiosk-stations-with-windows-7-and-windows8-itpro.aspx
in other words: you don't understand anything and you want to go round and round the mulberry bush. Well... here's something for ya. You are now on my Ignore list. And soon these forums will be purged of silly threads like this one and whiners and complainers can find somewhere else to drown their sorrows so that the forums can be returned to Help forums. Bye bye
I have been using Opera since the 1990s and have begun Link since it was formed, but now the Link system won't start even though my sign-on shows a valid state when I checked. Why is Opera's MyOpera Mail, Link, bookmark list on regular Opera screen, and other excellent features missing? Will Opera get back into it's excellent features a couple of years ago, or will I end up having to switch to Mozilla Firefox? (IE is idiotic and unsecure, and Chrome is not very alive.)
What kind of "restore" did you do? If it was just a "system restore", it would not have repaired damage to Opera program files or to any Opera files under a user account... "system restore" only restores critical system files (like the registry, critical windows files, drivers, etc). The only "true" way to restore a system to a month-earlier state would be via using an image's or file-backup's restoration program.
If you did only perform a "system restore", then a corruption or miss-adjustment problem within the Opera files themselves might still be present.
