taskbar applications

[viktoras didziulis]

i would appreciate a few hints on how do we create taskbar applications 
in Revolution on Windows. I.e. something like Revolution player, skype 
or anything like that where user sees an icon of a running application 
sitting in the taskbar. If he clicks that icon with mouse - context menu 
appears... How do we set application to be loaded on startup 
automatically ? I would like to add this option to preferences of my 
app, will it have to mess with windows xp registry or are there other 
ways? Any hints, online tutorials also on how do we do this on Mac, Linux ?

Many thanks in advance!
