Hide Mouse Cursor in Opera Browser

many ways to hide cursor in web browser, and i believe the reason is only to use for specified device/pc
– by using css (cursor none, cursor url blank transparent 1px image file )
– by using javascript (augmented by image)
– by using opera ini file setting

too bad none of those are work. I guess opera dev guys let this happen so they can have advantage from custom opera license (just my thought).
The last hope to hide opera cursor is to replace OS cursor, but this is rise more trouble for other program that need mouse visibility.

The wise solution is to replace rarely use cursor type

Help Cursor

this type of cursor is rarely use and yet supported in CSS

1. Change your mouse setting, replace help mouse with blank *.cur file (please make your own file)

2. put CSS code
* {cursor:help;}
