Applet - Drag and Drop

Hi,

I have a html page which has an embedded applet and few other html components. I came across the following scenario.

1. Drag the mouse from inside the applet to the embedding html
2. Release the mouse on the html page
3. I have handled the mouseup event on the html body element. But when i released the mouse on the html page to end the drag that i started from the applet, the mouseup event is not fired.
4. Even after i dragged the mouse outside the applet mousedragged event is fired on the applet and when i release the mouse outside the applet the mousereleased event is fired on the applet.

I don't understand why is this happening, why is the html not notified of the mouseup event when i start a drag from the applet and drop it on the html page. Instead the events are fired on the applet.

I've never tried this, but I very much doubt that mouse operations started in one of the environments (JavaScript and applet) are visible by the other.
