the only thing i can imagine being useful is a "direction" in which the menu 
should try and position itself relative to the position passed in: up, down, 
left or right. this would solve the issue your seeing for the case where the 
menu is rendered by the application.

it's not really a workaround: it is a better way to do this (just as the new 
systray spec is a better way to do it compared to the xembed method :). the 
menu really ought to be rendered by the visualization. it guarantees 

we're really trying to get apps away from rendering anything on their own that 
will get shown in the system tray or other places the status notifier items 
will be integrated into the UI.

that would mean having to go through an change all \n to <br/>, and messages 
would have to be careful about not including stray \n characters. it would be 
much easier and clearer to simply require the application to pass in 
consistently marked-up text with no processing of the text (only display) on 
the visualization side.

agreed on both points.

i doubt that is likely, but i do agree that it certainly couldn't hurt to add 
that to the spec for completeness' sakes.
