As some of us have found out, Opera 12.02 is common just now for lagging on web pages, this has been confirmed by Opera themselves, however the answer was to update from 12.02 to 12.11, but after I attempted to update the browser and when the browser shut down to install the update an error appeared and the windows error would not disappear no matter what, so I needed to do a re-boot.

Would this problem be because of the method I used to update given that I use the latest KernelEx ?

Absolutely! But depending on the error, other methods might also produce similiar results.

The 12.11 installer may still be on your HDD; it not, download it manually from the Opera site and exit Opera.

* Close all other apps and run the installer from Explorer.

+ You may need to try various KernelEx modes.

+ You may also need Kexstubs.

+ You may need to try a portable version of Opera.

* You do need to report the text of any error messages so we can figure out how to prevent or avoid them.
