Positioning a ContextMenu

Hi there,

has someone a code snippet for placing a ContextMenu at an arbitrary x/y position eg. on a tab? (including menu init please). If I use just the pattern with predefined divs as contextual areas, it is too static on the one hand and it seems that I am blocking other functionality in those areas.

The showContextMenu(x,y) method looks good at first glance, but I failed here, nothing happens.

Thx in advance, Pit.
