is there a problem with mouse right button recognizing

[patrick]

Hye,
I implement a context menu and then I must capture right button click
of the mouse.
I use mousecontext type in a addEvent.
It works fine with FireFox 3, IE7 and Safari but it seems that it's
not working on Opera.
the "mousecontext" type is not recognized in Opera 9.52.
Do you know whether it's a know problem or do you have some
information about this ?

Thanks in advance to your help
