Sometimes, after you install Sun JavaVM when MS JavaVM is also installed, some applications will not work correctly.
You can disable Sun JavaVM to use the MS JavaVM based application that works with your web browser.
(When you install Sun JavaVM, the Sun JavaVM settings are automatically switched on)
How to set Sun JavaVM off
Click 'Start' and then 'Setting' and select 'Control Panel'
(Depending on the Operating System you are using, the menu name and direction maybe slightly different.)
Select 'Internet Properties'. Check off 'Java (Sun) in the 'Advanced' tab.
Click 'OK' and restart your computer.
