[OpenLayers-Users] Right-click menu

[Graham Davis]

While you can figure out what mouse button was pressed that way, I 
couldn't figure out how to prevent the browser's contextmenu from 
appearing without adding the function for the oncontextmenu event.  The 
browser's context menu seems to fire and appear before the OpenLayers 
mousedown function is called, so I couldn't just stop the event.... 
unless I missed something during my tests.  Have you been able to 
successfully stop the browser's right-click menu from appearing that way?
