Hello,
I use opera browser for web browsing.But my problem is after  starting opera my screen locks.Then no desktop icon works when I click with mouse.What can I do?
If this is the first time it happened on your Opera browser, try restarting your computer then try it again. I am using Opera for quite some time now and I’ve never experienced this one from the time I first used it. It is very unlikely to happen if your system is healthy and doesn’t have any problems especially in the file system.
If it’s still the same, check your computer for any sign of infection. Update your antivirus then run a full system scan on your whole computer.
If you are using Windows, make sure to scan the folder System Volume Information which is located in the root of every drive. To view this folder in Windows Explorer, change an option in Folder Options to make hidden files and folders visible. This folder is the favorite hotspot of most Trojan worms and will infect all the restore points that the folder contains.
You may also try doing a clean installation of the program just to restore it to its default configuration and fix any corrupted files that may have developed in the long run. Uninstall Opera then check your computer for any possible errors. Use a disk utility application to check the system. Install the application again after this then see if this fixes the problem.
You may also consider upgrading your present version to the latest version if you are still using an older one. You may install Opera 12.00 which works on Windows, Mac OS X, and Linux operating systems.
To download this latest version, you may visit Opera software. After downloading the file, uninstall your present version of Opera then run this newly downloaded installer to install Opera 12.
