Hi guys!
I had same problems as davews:
Just to clarify. All pages load normally. However with any page that uses java applets the applets do not appear to load at all - on Firefox you get a popup asking you permission to run the applet, no sign of that in Opera. eg the Independent crossword site: http://www.independent.co.uk/extras/puzzles/crosswords/?crosswordType=cryptic where the crossword, which is run in an applet, fails to load. Java was updated via the Java control panel interface and clearly came from oracle. Opera 12.16 on Windows 7 x64.
If you have installed 64-bit Java version, but your web browser is 32-bit, then you should also install 32-bit Java version, as is prompted on this page on Java website: http://java.com/en/download/manual.jsp
We have detected you may be viewing this page in a 32-bit browser. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers.
It helps in my case
Cheers!
